I had a few nights of insomnia at the begining but also weekends where i was in bed for 20 hours a day asleep .. after about two or three weeks waking up on a saturday was so snuggly and the resting was really deep ..
all those weekends knocking back bottles of spirits and wine took their toll and i think it took a couple of months before my sleeping was at a reasonable medium .. which for me is about one night of poor sleep a week and 6 good'uns .
