my roomates want me to drink with them but am unsure of it because my first time when i drinked i got too much and woke up in a hotel room not remember how i got there at all how do i know how much is too much? i am getting tired of them trying to get me to do it all the time so i think maybe do it once so they will shut up about it and not bother me more about it? what should i think about before drinking???
