Alcohol will be there and i kind of wish i didnt agree to go

I don't like alcohol but people always push me to have a drink till I eventually cave. I'm such a lightweight. I always get sick

Tbh the people I'm going with I've been to Vegas with and they didn't really push it that hard then. I'm sure it'll be fine. But I just dislike everything about being drunk, I hate being not sober around other people anyway
