I think it's different for everyone. Sometimes when I clean up I can't sleep at all for a month or more but this time I've been sleeping most nights. I was kinda down today so thats probably why I'm up tonight. I just remember what my sponser says, nobody dies from lack of sleep. I've got 30 days in now but have only had a few all nighters this time. Some suggest talking to our HP so as to make use of the time but this place has lots of ESH as well. Hang in there it gets better.
