I was fine up until this weekend. I'm 3 weeks into my quit and now all I want to do is sleep. This weekend all I did was go from my bed to the sofa and back to bed again. I've always been an early riser but now I don't want to get up. Has anyone else had this issue? I typically get about 6 hours of sleep a night but this weekend I bet I slept about 18 out of 24 hours both days.
