I have found the wonder cure for sleep, melatonin. It is safe to take nightly (I checked with my doctor) and can be bought in any health store and it's very inexpensive. I also take valerian root with it because it helps make for a restful sleep. I take it nightly because my medications have ruined my sleep, I fall asleep quickly, sleep well and don't wake up feeling groggy. It has saved my life. I haven't slept this well in years.
