I tried initially on my own and never really got past a few days at a time. It gutted me because I always felt that I had more 'control', so why couldn't I do this?
It took more than a year to really get on track, I never would've thought I'd get to be two and half years sober.
As for lacking energy, the recovery/healing process uses a lot of energy in the beginning. I used to justify that when I was drinking I did more things, but that wasn't the case towards the end, I just used to sit there and get drunk/'para'.
If it's a few day to day things that need doing, I've seen suggestions here before that maybe you can put some of the money you save from not drinking towards getting some hired help. You will eventually start to feel fitter and like doing more.
