SoberD, Congrats on 23 days! That is fantastic!
I definitely spent a lot of time napping the first month and a half, despite sleeping better than I was when I was drinking. (sober sleep is truly my favorite thing in the whole world right now)! I'm at 11 weeks , and I would say in the last month and a half or so, the napping seems to be lessening. I also am sleeping much better (less waking up and then falling back to sleep), which may be why.
Unless you feel depressed or blue, I'd take the napping as just a sign that your body is rejuvenating itself.
