Although this may be old news to some, I will post it anyway. A friend recently loaned me a book called "Melatonin..Nature's Sleeping Pill"...by Ray Sahelian, MD..Published by..'Be Happier Press', PO Box 12619...Marina Del Ray, CA 90295...ISBN 0-9639755-7-9. First printed in April (3,000 copies) & then June (20,000 copies) 1995. It is in paperback, price listed on back is $13.95. People here (where I am) are passing it around, there seems to be lots of interest. Although the primary focus (of the book) is as a sleeping aid, there is much other reference to other possible effects, including brief references to PD, Alzheimer's, & Lou Gehrig's (and other conditions). It seems quite well written, got some impressive reviews (printed in the book), and relates stories from a selection of 200+ users. It may "over-hype" the concept, but it was worth reading, and I intend to get some (Melatonin) soon to see just what it may or may not do (for both of us). p.s. I sure hope this does not look like a 'spam'! I just wanted to pass it along to all of you..I have received SO MUCH wonderful information & support from this list..Thank You to all!! ....Roberta
