first time drinking

hi! so i’ve never touched alcohol a day in my life, and i’m going to a party where i wanna try for the first time. i’ve had weed but edibles specifically messed me up pretty bad. i don’t want to lose control and i don’t want to be nauseous or throw up (i have emetophobia), but a major issue is that i’m on prozac so while a single shot may be enough to get buzzed the first time, where should i max out while i’m on prozac?
