I don't sleep when I drink I pass out. It's like I just wouldnt seem to hit those deeper sleep stages. Many times I'd wake up a few hours completely exhausted and unable to really do anything. I remember at one stage I would drink early on saturday and pass out during the prime time college football game. Then I'd come to and the replay of it would be on in the middle of the night. I use to count on it after a while. Delighted I didn't miss the football game and have something to do now that I cant sleep. The part of the game I did see in real time I was probably in a blackout anyway.
These days I try for about 7 hours. Then I try for at least 20 minutes of meditation. My problem is i always want to watch just one more show on Netflix or something and I stay up late and have a long commute to work. I have even less time than i do money!
