Thanks everyone for so many great responses.
I'm really hoping this feeling will last. I was so depressed for so long, maybe this is what a normal person feels like? Who knows. I definitely don't feel like I can have any drinks. I know that I can't, and I don't even want to. This time around, I don't seem to be forgetting all the hangovers and regrets. I won't let myself. I also don't feel like I don't have to do the work. I'm not going to any AA meetings or doing the steps or anything, but I'm still consistently reading around here and posting, plus the majority of my free time I spend reading memoirs of recovery. I also did buy the AA book to read, out of curiosity. It's an interesting read so far.
I'll be on the lookout if I lose these feelings to make sure I work even harder at my sobriety. Right now, I'll use my good feelings to make some progress and work on myself even more.
Thanks again!
