I wonder too if sleep--or lack of it--has anything to do with the memory loss so many of us experience. I used to sleep like a log, eight or nine full hours almost every night, and now I'm lucky if I get more than six. It could be aging (I'm pushing 55), but I used to be able to sleep without taking any meds at all, and now I'm taking Ativan plus Geodon plus melatonin, and I STILL have trouble getting to sleep and staying that way. Go figure.
