Good source of information about 5-HTP, but I would like some things to be explained deeper.

I decided to read this prior to trying out 5HTP for the 1st time.

This book is full of information on 5-HTP, I love this stuff. It does help with sleep. My only one minor complaint is that it definitly looked like the book was old and worn a bit.
