I find booze to be a useful tool, properly administered. I favor vodka, which is the purist's beverage: nothing more than ethanol diluted with water. ("Vodka" is a diminutive Russian word for "water".) The drink takes the edge off; I may actually talk to people without the usual trepidation. Of course, after I come down to earth, I feel embarrassed for whatever stupid things I said. But on the whole, the occasional drunken interlude is probably useful. Sort of like a little vacation.
FWIW, for me, a hangover is less likely if I stick to quality vodka (I like Tito's), don't overdo it, and get the alcohol out of my system before I sleep. I prefer to drink without a lot of food in my stomach, which results in the alcohol going into and out of my blood more quickly. In my experience, drinking on a full stomach is more troublesome, because I'm not reacting to the alcohol as quickly, so there's less control over the level of inebriation or how much time it lasts.
Everyone reacts differently. Some people shouldn't drink, or there's no need. But I'm glad to have it in my bag of tricks.
