Me too. I've been sober exactly one week today. I thought I'd have more energy but from what I've been reading here, it takes time. We've been abusing our bodies and need to take care of ourselves... eating property, getting enough rest, exercising, taking vitamins, etc.
I do feel good when I wake up in the morning and say "hey, I didn't drink last night?" Even though I'm still dragging my butt around the house and the office.
