My dose is 1/2mg Melatonin and Inositol and Gaba which are in my sleep combo whch is posted here in a couple places. I sleep good, 8+ hrs with one wake up at 3AM or so for bathroom. I buy 1mg source naturals tablets and break in half. I have some glycine headed my way and will be taking some as I also hear it's helpful for arthritis.

BTW: I start my melatonin etc at 7:30PM which starts preparing body for sleep at 11PM or a little earlier.
