Glad to see the thread bumped. I'm now a little over 6 months booze/beer free. I'm still pretty certain it was one of the best decisions of my life. Down 27 pounds(I attribute about half that to the lack of alcohol) since August. I had to go buy all new dress clothes for work trips since my pants are now 2" too big.
Sleep continues to be great. I can get a square 7-8 hours, wake up early and exercise for a bit, then go about the the day with plenty of energy.
Another big change is my digestive system. No urgent dirty morning beer poop, no bloat, far less gas. Everything comes out in a calm and timely manner.

Sorry to bring that one up but it was worth mentioning.
