I'm on day 18 right now. I went from no sleep for days, to now "sorta sleeping" 3-4 hours of continuous sleep. I've been taking catnaps in the late morning hours, which is something so foreign to me! When I was actively drinking, I never napped. I am on a low dose beta blocker to help with the BP, so that could be kicking my rear or it's in combination with the healing process.
