Hi Sammy!
Welcome aboard and congratulations on Day 1.
The people on here are really grat and have allot of good advice to share.
You said you don't know what you can do for fun now. Was drinking really all that much fun? The hangovers were fun? The embaressing situations you put yourself into were fun? The way you humiliated yourself was fun? I don't think so.
Personally I think that I need a bit of time to adjust to life without alcohol. But I know allot, probably the vast majority, on here all have fun lives. So their must be other interesting and fun things to do out their other then drinking.
Let us know how you get on.
Take care.
