Hi Simon
OSA is Obstructive Sleep Apnea. That is when a person stops breathing while asleep. It is not behavioral, is it mechanical, neurological, or in my case, both. When I fall asleep, the muscles relax to a point that my air passages close. After a while I waske up enouph to I fight for life, gasp for breath, and drowse back down again. It repeats over and over, about 30 times per hour.
Unfortunately, the use of paraliminals is limited for that. I used them to get used to sleeping with the CPAP machine and mask strrapped to my face, though.
RE the vitamins- yeah, I have been into alternative health and supplements since I first found a "Whole Earth Catalogue" on a bus in 1973. Made it my business for many years, but the retail natural health industry changed and became mainstream consumerist and politicaly different than the values I want to live. Still deal in some import/export, and still keep up witht he research, but my true calling is counseling.
If you can safely take relaxants, (I cant with my condition) and if it is only occasionaly you might try Valerian Root (Smells like a high school jocks locker, though) but is works for many people. Kava is good, too, if it is legal where you live.
Let us know how the Delta Sleep System works for you!
