I hardly slept for years after I got ME. You know the story, lay down dead tired but wide awake, finally drift off only to wake again in a couple of hours. Then, the long wait for dawn. Immunepro, a superior form of whey protein, greatly helped. Taken in a couple ounces of water just before bed usually gets me to sleep and keeps me there much longer than before. It you try it you should know it can be a pain to mix. Use something like a tall bottle, pour in small amount of water FIRST, then a scoop or two of Immunepro, and swoop it around in the container like a little tornado. Or, I guess you could use a mixer. The other thing you might try, is Osteo-Strontium Complex(not to be confused with strontium 90 isotope, that's a whole different way of putting yourself to sleep) by Nutricology and in the powder form(the tablets didn't work for me at all). Again, I took it just before bed. Hope this helps some of you. Not sleeping is its own nightmare.
