Lisa, I gather from your post that Jeff is finding NADH beneficial. If you can be specific, keep us up to date. BTW, I started Eldepryl a couple of days ago (following the most recent favorable journal report) and was startled to find that I felt better, with more physical and mental energy, on the very first day. Like many other drugs, nobody knows how this stuff really works, but why quibble? Cheers, Joe J. R. Bruman (818) 789-3694 3527 Cody Road Sherman Oaks CA 91403
