Personally, I am so much more happier these days that no matter what I am doing (even at work) I have fun.
Driving home from having dinner with my parents the other night, my girls and I spent most of the time laughing to the point of tears rolling down our faces. That would not have happened a few months ago because a) I would not have been driving and b) if i was in a car with others i would probably be drunk and muttering something totally unintelligent....lol
I guess what I am trying to say is give it time, the fun will come when you are happier with yourself. Good on you for recognising your drinking is a problem before it was too late.
Life is worth living, one day at a time....sober
