Why risk it?
I sure wish I had decided to stop drinking when I was 22..... it took me another 33 years! If you are binging every weekend then I'd say it could easily become a problem for you.
There is no reason that you cant have fun and friends w/o alcohol. Take a good look at your friends, are they 'TRUE FRIENDS' or just drinking buddies? They could be both but would you trust them to take care of your house and pets or car if you had to get away for a while?
You are at a crossroads in your life and you have posed a very important question that could effect the rest of your life. Keep posting here and reading the accounts of some of us who have had decades of experience dealing with alcoholism. It's up to you but I can GUARANTEE that a life w/o alcohol will be INFINITELY better than the life of a drunk or binger.
