I know this is a thread about AVRT but I would like to respond to Zenchaser just for this post.
Zenchaser sorry to hear you're feeling flat, I agree with others that if you give it time your natural enjoyment of life will return. I know what it's like to feel like you don't enjoy anything, but sooner or later, could even be today, you will find yourself doing something that you find pleasant, could be reading, cooking, exercise, taking care of the house etc and you'll realise there is enjoyment to be had when sober, it might just take a little while to get there.
Personally I get that hedonistic buzz from weight training, it works for others too. It's about getting that endorphin rush from physical exercise (The AA'ers would tell me that getting a buzz from weight training isn't acting 'sober')
Do you have any hobbies you enjoy sober? If so, get back into them, find that fascination and enjoyment from the small things in life that alcohol/drugs blinded you to.
