I just wanted to chime in about the 5HTP. I've been taking it for a while but always in the am. I read something that made me decide to try to taking it in pm instead to see if it would help me stay asleep. Anyhow, it has been helping, I'm not waking up nearly as much as I was, feeling at bit better in the am, so I do think it is making a difference. Happy, Happy! I buy most of my supplements from an online and catalogue order company called Swanson's vitamins. The prices are better and the quality is good. Hope this is helpful.
