No one if forcing you anyway. Though I might sometime express my utter hate for something, I am not a priest nor am I any police. I am not going to stop anyone from from doing what they want. It's your life, so take responsibility for it and what you do. I'm not going to be around to stop you. What you do it your business alone.
That mentioned, it is fine to encourage or recommend someone to stop, but not to force.
So carry on.
Sure, you can do that. But I wouldn't recommend it to anyone. It's a very bad suggestion, as well, because it encourages the use of a very bad habit.
Drinking is a big problem in today's society, therefore it is within my humble opinion that we shouldn't encourage someone to do it.
And I really can not find any fun in getting drunk. Sure, you can go out and have fun. Sure, you can go to bars or whatever, talk, do something, have fun. But that doesn't mean you have to drink.
