I use Melatonin. I get it chewable from Trader Joes. It tastes great. But, it does not always work. I have not slept well for the last week. Took some Ambien for a few nights but I do not want to become dependent on it. Last three nights I have just "dozed" Finally got sleep after 4:30 am as well. I am tired. Tonight may have to be an Ambien night, I can't do this too many nights in a row!!!
