I can have 3-4 hard ciders, vodka mixed drinks or other alcoholic beverage and have the same sense of degree of inebriation as I do with 2 glasses (or less) of red wine. Why is this? It is a shame because I heart red wine and would love to pour myself another glass, but if I do I am toast for the rest of the night 
Does it make you forget you still need her so?
I’m so tempted to ask “Where else would the wine go?” but then there are some people who put wine into parts of their body other than the head, so let’s not go there.
More seriously… hard ciders and mixed drinks are likely to have a lower alcohol content. It could be as low as 3-4% alcohol, so you get “one drink” in a 12 oz serving. Wine can be 12-15% alcohol (and sometimes even a little higher) and you get “one drink” in a 5 oz serving… but because you’re pouring wine into a wine glass that is often much larger than 5 oz, it’s easy to over pour. When one friend pointed this out to me, I did some measuring and realized that I tend to pour about 8 oz of wine per glass. So if I was doing the pouring, 2 glasses of wine could easily have the alcohol content of 4-6 beers or mixed drinks.
On a more anecdotal note, my father insisted that red wine made him feel more drunk because of a reaction with sulfites.
Personal anecdote: I get worse hangovers from red wine than anything else. I have transitioned to martinis and/or other white liquors for when I wish to get drunk, and reserve red wines, whiskeys and dark rums for when I just want a tasty drink.
Competing anecdote: I get worse hangovers from anything other than red wine. I think it’s because everything else that I can drink has a lot more sugar in it (including the whites that I like) and I get hangovers as much from overdoing the sugar as the alcohol. ETA: but then again there’s even less sugar in straight liquor than in red wine, but I don’t drink straight liquor. If I did I might get a bad hangover anyway if I forget to hydrate myself, but i’ve never tried, at least when I was drinking to get drunk rather than drinking to sample a small amount of special liquor.
