(Please help!) This might be one of the most stupid questions in this forum but its a genuine concern

yeah there's a guy I know currently in i-banking at Chicago (Harvard grad, Booth MBA). Pretty fun guy. Can't drink either due to medical reasons but he's pretty much full on into drugs (MDMa, cocaine etc)...I think that's what he uses to get a kick 

muh "allergy" to alcohol

if someone brings up that you're not drinking, just state the truth, which is that you have a medical condition that prevents you from consuming alcohol. if they judge or criticize you for that reason, you probably wouldn't want to work with those assholes anyway

Don't start about medical bullshit. Buy one of these huge, showy sportswatches and tell everybody you are training for IronMan/marathon. As an analyst you will not talk to clients anyway.

I think you should be totally fine. While it’s definitely not really common, there are enough people for religious/medical/other personal reasons who don’t drink that it shouldn’t be an issue. You can still hang out with others and just get soda to drink instead of alcohol.

I think you should be fine. I am a first year analyst (female) and I don't drink because of health reasons (don't have any medical issues. Alcohol is just bad for the body). Last year during my internship, my group used to have a happy hour every week and there were quite a few of us who didn't drink (you can just get water or a diet coke). My group is very fratty and the frat dudes have their parties/ late night drinking sessions etc that they don't invite any women too so there's that tho 

Quite frankly most of the responses are not all that helpful.  You are an adult and so is everyone else you are working with.  No one will really give you shit for not drinking ( there maybe the occasional "why are you not drinking bro?"). You can have a completely fulfilling and strong career without alcohol, drugs and any other part of the partied out lifestyle people think that comes with banking.
