I agree about the foods to avoid. I gave up alcohol because even one small glass of wine in the afternoon could keep me awake at night.
Turkey has tryptophen so that would be good for sleep.
I drink a cup of chamomile tea in the evening and take 3 calcium/magnesium/VitaminD capsules each night. I also had restless leg syndrome and after some research found out that iron deficiency can cause that. I started taking an iron pill before bed too and no more problems with that.
If you have problems sleeping, try meditation. I have been meditating for a while now (after several years of sleep problems) and suddenly I was sleeping like a rock at night.
Also, daily exercise works wonders.
These aren't foods, I know, but really the sleep issue won't be helped that much by foods (more which to avoid)
