I was very, very tired for the first month and a half, despite getting plenty of sleep. I am currently on Day 66 (over 2 months). I get plenty of uninterrupted sleep (at least 8 hours a night) without any sleep aids and I have plenty of energy in the morning and during the day. Just remember to eat right and get exercise and be patient with your body, which has been taxed for a long time with alcohol abuse.
