Well I am in my sixth week and while I feel fantastic overall, I'm still not sleeping worth a crap and am often tired. One thing alcohol did for me was wake me up. I know that my tiredness is part of depression, which I plan to resume treating once I'm more solid with not drinking.
Welcome to SR, newtothis. This may also be something you should talk to your doctor about. Could be something as basic as getting some aerobic exercise (makes me feel tons better) and taking a multivitamin. How long have you been sober?
