Prevention is the #1 way to not go down this road!! I think a glass of wine per night is fine but once you start thinking "I need to be drunk" is when things start getting shaky. I can relate, I used to always drink for the sole reason of being drunk and getting that "high" but I think what you need to do is think of the negative effects (hangover, getting really tired after it, etc) and also try to find some other stuff to keep you busy and happy. I found that for me, I would drink specifically to become happy but once I found some other stuff that made me excited I didn't really care for the alcohol anymore!
