I’m a 21 year old girl, 5’3 and weigh about 115. I’ve drank and gotten tipsy before but honestly not much of a drinker so I haven’t gotten super drunk or thrown up or any of that. Would drinking at about 2 shots an hour or so be enough to get me ‘drunk’ but not like falling over/blacking out/throwing up?
I would recommend zero. Not only because you are both female and petite, too many of the people who've asked / posted such questions anonymously are actually underage.
I think 2 shots in an hour would easily get you at least tipsy, if not drunk. Drunk enough that you shouldn't drive at least. And, that's the first hour. If you kept on drinking 2 shots an hour for a while, you would be very drunk indeed, and probably get sick after a bit.
Two shots an hour sounds like a good idea, but I learned from experience that I have had enough to drink when I can no longer feel my nose. Really. When I can no longer tell it is there without touching it, I've had enough. BTW, I once wrote software for a weight loss company, and the algorithm for desirable weight was 100# plus 5 pounds for each additional inch. Your 105 at 5'3" is perfect.
