psily,
On the sleep problems. I believe I would be on my last legs before death now, had I not quit 9 months ago. It felt like it then. I still have some sleep issues, I sleep four hours then wake for two then go back. Sometimes I can't sleep but most times I get all I need and feel pretty good all the time.
Here's my point for you, and my attitude when MY sleep was really hard to get. Life is short followed by the long sleep, the dirt nap, and I believe I can catch up then. If I drink now, to sleep, instead of decades I get the long one sooner. Much sooner.
I believe now I can worry about my catching up later. Much later.
