For the first time in years, I'm sleeping 9 hours a night. I honestly think it was my dependence on cigarettes that had me getting up so early. It wasn't unusual for me to get out of bed at 2 or 3 in the morning to have a smoke. That's just sad and pathetic. It wasn't the craving that woke me up. I would wake up to go to the bathroom but as soon as I was awake, the cravings would start. I'd have 3 or 4 cigarettes which of course overstimulated me. Then I had to have the morning coffee to go with it. I was functioning on 5-6 hours of sleep at night. I'm not getting up as often to go to the bathroom now but if I do, I go right back to sleep. It is so much easier to function now that I'm getting enough rest!
