I had trouble sleeping when I first got sober.It actually seems to be pretty common among many people during the first couple of weeks of recovery.
Very often my mind would race and my thoughts would all seem to fly off in different directions at the same time.Alcohol was one of the things that used to help to quiet the clamor in my head.
Without alcohol so many thought would just keep flying around inside my head that I found sleep virtually impossible.
Talking with other people that had experienced what I was going through helped to reassure me that it was a phase of recovery that would pass eventually.
I did a lot of reading during those first nights of sleeplessness.I read the AA Big Book and just about every pamphlet that AA had ever published at the time.
Someone also introduced me to "Celestial Seasons Sleepy Time" tea and I found it very soothing and it also helped me to sleep.
It is all natural and safe and most major supermarkets should have it.
As long as we stay focused on our recovery the sleeplessness will pass.
Peter.
