Have you tried cold brew? It is much less acidic and bitter than hot brewing. I don’t tolerate the hot brew myself much any more, other than the rare espresso.
Generally, one mug of French pressed, medium roast coffee with cream and sugar every morning (around 12 ounces), plus one travel mug (not quite full, 16 oz max capacity) of English breakfast tea, bag removed after 5 minutes, which I’ll sip on through the morning and convert to iced tea by adding ice as the volume drops.
Maaaaaybe one extra hit (gnerally similar to one of the above) on days with insufficient sleep, or poor sleep. And I’ve stopped having any after 4pm unless I’m travelling or have another reason to try to stay awake late. I find that I need 6 hours after any equivalent size dosage is what’s needed for me to be able to sleep.
It’s not that I feel more awake, but sleep doesn’t come. Which is to be expected of the drug in question. YMMV.
I have two 10-oz cups of moka pot coffee every morning. I use the reducer disk which cuts the amount of grounds in half, but it’s still plenty strong enough for me. (my usual brand is Cafe Bustelo Espresso ground)
One to two cups of coffee (or one in a travel mug) every morning, drunk black. I very rarely will have a caffeinated pop (usually Coke Zero) at a restaurant.
About 1.5 liters of black tea, which is three 16-oz insulated mugs, of varying degrees of zip per day most days, each mugful with a splash of whole milk and two packets of stevia blend. I am a little more reliant on this than I would like, on days when for some reason I can’t indulge I feel a little sluggish at times during the day. I start at around 10 in the morning and usually am finished by about 4 in the afternoon. No caffeine after 5 pm.
Caffeine started to affect me badly (stomach issues and nighttime headaches), so I gave up my daily double espresso and switched to black tea. After awhile, it became evident that even black tea had too much caffeine for me, so I switched to decaf Assam tea. I drink a big mug of strong decaf black Assam every morning, and I can still feel the little smidgen of caffeine it contains.
But every once in awhile, I’ll challenge my body with a double espresso half-caf. I only do this once or twice a month, and that seems to be about my limit for how much coffee I can deal with.
To think that I used to be able to drink a big cup or two of strong coffee after dinner and not feel it at all! That was about forty years ago, though.
My parents did that for most of their adult lives, and I never understood how they could do it.
I often grab a cold sweet coffee drink as I’m leaving the house in the morning. The latest ones were on sale and have 200mg.
I wash the sweet coffee down with a diet coke, and continue to sip diet cokes throughout the day. I average around 6 per day.
And I have a coworker who arrives around noon and brews a pot of ultra-caffeinated coffee. If I get a craving in the morning I put his leftovers in the microwave with some coconut creamer.
I’m highly intolerant to insufficient caffeine.
I first shared Taster’s Choice in the morning as a way to bond with my father. I was probably 7 y/o.
Pretty much a coffee achiever ever since.
But I don’t guzzle the stuff.
There’s a really nice roaster only about a mile from me. Their family owns a farm somewhere in Brazil, so they’re vertically integrated. I buy their espresso roast and make a French Press pot each morning. It’s about a 12oz cup each for my wife and me.
Weekends, we’ll tend to have a second cup.
After about noon … very rarely. I’ve never developed a perceptible tolerance to caffeine. A cup after dinner would make sleep an ill-fated endeavor for too many hours.
Couple times a year, I’ll stop for an espresso. We have a pretty good selection of indy places that attract the coffee geeks. I’m not one, but it’s good brew, to be sure.
Sometimes, my wife and I will kluge up a mocha by adding Stephen’s dark chocolate powder to it.
That’s … roughly akin to an ex-cigarette smoker’s first or second ciggy since having quit 
And my wife’s more fond of butter/Bulletproof coffee than I am, but … once in a while.
a lot
(Espresso) coffee and tea are probably my favorites.
Any time of day or night the fancy takes me (which is sometimes not at all, but most days I usually have some)
Not really… but I do not slam cups of coffee down like shots. If I do have 4 espressos (not a regular thing btw 
they will be consumed over hours.
Drinking a ludicrous amount of strong yet bad coffee does make me feel kind of nasty, I have to admit, but I don’t know if it is purely the caffeine in that case.
PS Upon reflection, drinking way too much caffeine I would say has a net affect of making you more tired, like there are fewer hours in the day.
I do not drink coffee or tea. Coffee has always tasted like roasted dirt and I can’t see the appeal. I used to have a can of pop, Pepsi or Mountain Dew on my desk when I was working. That costs me my teeth eventually.
I was dating a girl 30 years or so ago and she had some chocolate covered espresso beans and she left them on the table while she went to talk to someone. They tasted pretty good so I had about 9 beans. When she came back she asked me, “how many did you eat?” So I told her and she said we needed to get a deck of cards because I was not going to be sleeping tonight.
Noon the next day, and I am still a nervous wreck! Never felt so ill. And that was my last experiment with caffeine. I would rather snort an 8 ball of cocaine than go through that again.
For me, coffee is much more than a caffeine delivery system. If I could find a decaf bean that didn’t taste weird, I’d be happy to switch, at least in part.
I make a “12-cup” pot of drip coffee every morning and drink most of it. I believe that the coffeepot holds about 72 ounces; Mr. Legend’s mug holds about 12 ounces, and he generally drinks two cups, but about 4 ounces of that is milk, so he’s only getting about 16 ounces a day. There’s usually a trivial amount left in the pot at the end of the day. This means I’m drinking about 50 ounces of not-too-strong coffee per day. I’ll sometimes make it with 25% decaf, just as a gesture towards lowering my caffeine consumption. I try not to drink any after noon, but I do find myself having just one more cup as late as 2 p.m, especially in the winter.
After I was diagnosed with (mild) atrial fibrillation a few years ago, my cardiologist suggested that I might not need medication if I quit drinking coffee. After we talked, he told me he could support me continuing on medication and keeping my coffee habit if quitting would reduce my quality of life.
I gave up cigarettes, recreational drugs, and soft drinks. I just need this one thing.
Nowadays I usually have a cup of coffee in the morning before or with breakfast; I often have another one in the evening, maybe about 7PM or something. I might have one more cup somewhere in the day if we’re out and decide to take elevenses in a coffee shop or something.
This is significantly less than I was consuming a few years back when I was working an impossibly demanding and stressful job and I worked myself into a situation where I pretty much had to drink coffee constantly just to keep going; at that point, 12 cups a day was just the baseline and I couldn’t sleep unless I had a cup of coffee right before bedtime (that might not make any sense, but if I skipped that coffee, I would wake up in the middle of the night with a severe headache). It was a dependency.
Leaving that job was the path to dialling back the caffeine to the current level where I don’t think I am actually dependent on it at all any more, in fact I’m sure of it because there have been weeks when we were away or some other thing affected our routine and I didn’t have my coffee for days or a week, and it was fine. I mean, I missed it a bit because I like coffee, but only in the way that I would miss eating toast for breakfast if it wasn’t available.
I have a small Mr. Coffee, the “5 cup” kind. I have one of those every morning, and I’m good until tomorrow. I don’t know how much caffeine that is, but I use 5 Stewart’s Scoons of ground coffee to make it go.
One sugar-free Rockstar (16 oz) in the morning; then about 24 ounces of Twinings Irish Breakfast tea, followed by 24 ounces of Earl Grey or Yorkshire… Sometimes another 24 ounces of one of those, sometimes not, depends how close to leaving the office it is when I finish the second serving of tea. Generally no more caffeine the rest of the day.
I used to drink three or four liters of Diet Mountain Dew each day.
I have 24 ounces of coffee from a French press every day. That first cup while I do worlde is my favorite part of the day. I can’t have any caffeine after noon, or I don’t sleep well.
Several times a day, I drink Lipton tea in a a pint like this:

I have one cup of tea a day, usually in the morning, but not right after I get up (currently, it’s at about 9:30, after getting up at around 6:30). I could drink decaf, but I find a difference in flavor (which might be purely imaginary; I’ve never blind-tested it).
Occasionally, I’ll also have some cola. Generally not more than 12 oz, and never after 3 PM.
I’ve found that caffeine in the evening does keep me awake, but it also kills my attention span, plus I need to pee a lot, so it doesn’t lead to any net productivity, even in the short run (and of course, the next morning, I’d either need to sleep in, or be tired then, so even worse in the long run).
One 12 oz cup of coffee in the morning, sometimes topped off. Rarely two. One can of Coke or Mountain Dew with lunch. Iced tea for dinner. One cup of coffee or one can of soda with dessert, depending on the type of dessert/snack. That’s about it.
I have a can of Diet Coke every day with my lunch and that’s it other than a small amount of chocolate I might eat every day.
