I do agree that everything should be in moderation but that's probably not the case with drugs and alcohol , I mean once you start , It's probably just a matter of time until you get addicted to it and you screw your life. It's better to stay away from these things . I never smoked or drink anything on my life and I'm just fine , If I have problems or I celebrate with something , I don't see how alcohol will make me feel better.
Unfortunately the present world is full of different problems. Related to this is a large amount of stress the person is experiencing. Don't fight them face a nervous breakdown. Helps to fight the alcohol. So choose.
