Thanks again KingYoshi. That helps me a lot. The more I think about it, I don't recall ever experiencing SP. We are definately all wired slightly different. I really like your strategy of setting alarms thru the night. My wife probably wouldn't be real thrilled about that, but the the logic makes sense. I recently learned of the "Zeo." I'd like to get one of those as soon as funds allow so I can get a clear picture of my sleep cycles. That thing would be worth $200 to me just for that.
