Melatonin has helped me alot for sleep. I am also going to start taking it in the late afternoon on the theory that it will help with my diurnal cyclical depression.

Chamomile tea. That is the only thing that got me through drug and alcohol treatment. I broke up two tea bags and drank it herbs and all. I was very tempted to roll it up and smoke it. They couldn't keep enough of it because we were all drinking gallons of it. It works.

I am sure in the section on "other treatments" you can find lots of info and expertise. Just post in there and I am sure you will get lots of advice.
