If you’re of the age of majority, can pay for such a drink. Are able to prepare it to your liking, please write on paper, on your computer. Maybe text a couple acquaintances that:
“I choose of my own free will, of sound mind and judgement to ingest this drink and if I die don’t sue the manufacturers of the ingredients.”
Saves tax dollars, the docket, pain of your loved ones if it kills you. Win-win.
ETA: next time you go out to party and over drink and then choose to drive home, do the same.
@kjwrites, my very negative response was in no way meant as a jab at you, just at the drink itself. Why do you have to stay awake so long at night? If your job is at night, give up the dangerous drink and sleep more during your time off. If you are working two jobs or working and taking classes at night, try adjusting your schedule so you can sleep more. Drinking that drink on a long term basis is bad for health, end of story, and you need to stop. Were you my brother or a good friend, I would nag you relentlessly until you did so.
Maybe your body is trying to tell you something.
I think it’s screaming as loud as it can.
I don’t know if it comes it bottles; I get it in a can. So, what you’re saying is to remove some of the espresso. To make the drink - healthier, I would say - for me to ingest.
I write. I find that I’m more motivated when tired as I, as strange as it sounds, write more to avoid sleeping. Unfortunately, one cannot just stay up several nights in a row without passing the fuck out, so I came up with an alternative. That being said, this particular brew is new (has more espresso than usual [my usual being 5 shots] and has more red bull than usual [my usual being half a can]) and I’m experimenting. If you have a better alternative, god please tell me. 
Yes, I do; get more sleep! So, it takes you 2 years to write a great book instead of one. At least you’ll be alive to see how well it sells.
Can you provide a sample of your hopped up on caffeine writing? I want to see something…
Pro tip: while it may subjectively seem like you are being productive staying up writing while on crystal meth or whatever you have concocted, it does not actually work that way, you just end up with crap.
Thinking the handwriting will be like a seismograph on Richter 9.9+ 
You’re not morally required but it would be nice if someone you know tells us what happened to you.
Just remember, you don’t have to have a heart attack to damage your heart. You could tear a valve that requires open heart surgery to repair. Been there. done that.
Alright. I wrote the first this morning and the second about a week ago.
Non-caffeinated writing: Understanding her situation didn’t help Eden empathize with her sister in any way, shape, or form. Yes, objectively, Ariel had been enslaved and used for her gifts. But Eden was left alone, believing herself the last of her kind because Ariel was scared. Scared of trusting in her own blood to save her. Eden had needed someone. Someone to show her what she was doing wrong and write and someone to talk about boys and school and bullies. Eden was a child and Ariel was an adult. Understanding only made Eden hate her more.
Caffeinated writing: The lab is cold. It’s strange that the coldness was what hit her first, but it was all she could focus on for minutes on end. Then the talking crept in. Muttering scientists, she thought even as vision slowly came back. Then she could see, feel, hear… Her senses were working. That much was obvious. The man leaned down in front of her. She was naked, she realized as a blanket was thrown over her shivering body. The man smiled at her and the smile was full of kindness. She blinked. Her memory was hazy but she could see a bright light; hear talking; smell something burning; feel the pain. Over and over, this one sight in her mind. She ignored it, yanking herself to the present, staring at the doctor.
I did a little poking around on google (keep in mind I’m an engineer and am in no way whatsoever anything even remotely close to a medical professional). According to Mr. Google, the effects of long term use of high levels of caffeine are insomnia (you already have that one), thinning of bones which will make you significantly more susceptible to fractures, anxiety, high blood pressure, stomach acidity and irritation, dehydration (since it will make you urinate a lot), and fatigue.
That last one is important. If you are using these ultra-high levels of caffeine as a pick-me-up, you are actually making your fatigue levels much worse in the long term.
As someone who has withdrawn completely from much more sane levels of caffeine (because tea was one of the most likely suspects in causing my kidney stones, and let me tell you it doesn’t take too many of those to convince you to change your diet), withdrawing too quickly is painful. I got massive caffeine headaches if I tried to quit too quickly. Slowly consuming less and less was a lot easier. I also felt a bit fuzzy in the brain, which isn’t good when the worst case for me screwing up on my job is basically a Bhopal disaster type of event. Eventually though, your brain recovers and you no longer need the caffeine to think clearly.
Since you are a writer, slowly reducing your caffeine levels will probably have a negative impact on your writing in the short term. Considering the massive doses of caffeine that you are currently on, it’s probably going to take a while to wean your brain off of the caffeine it currently needs to be alert and fully functional.
As long as you are not consuming this much caffeine specifically for the purpose of intentionally harming yourself, I don’t think there is any legal issue. But then I am an engineer and not a lawyer.
Well…
My writing is shit all the time. But when I’m high on goof balls it seems so brilliant.
You are morally your own boss. Do as you must. Legally, unless your family sues after your demise, I think you’re allowed to drink Drano if you choose. I wouldn’t worry about that at all.
Medically. Hmmm? I think your spinning a roulette wheel. For nothing, I can see by your samples.
(Not meant as a writing critique, I have none of those skills)
That’s not screaming.
It’s vibration at an audible frequency.
Which is the very definition of screaming.
All I really did was read the OP, and now I’m in atrial fibrillation.
Great. Just … great.
As an artist/writer/teacher, I’ve read a lot, and I don’t see much of a difference in the quality of your two writing examples.
You don’t have to suffer for your art. You might feel more creative “on the edge”, but getting more sleep and spending more time writing works better.
Practice and experience, and getting feedback from people who know what they’re doing are the best ways to write compelling shit.
And doesn’t taste like Red Bull in espresso…
Plus, there may be a cumulative effect, if you take your next dose before the previous one is out of your system.
