Well I ahve had a history of depression, drug addiction and eating disorders, and had recetnly sunk into a really deep depression. Had taken Prozac in the past but didn't want to go that route again becuase of the expense. At the suggestion of a friend i started taking 5-HTP and began Atkins. BOOM! I'm a different person! Eating disorder is at bay, mood is stable - with periods of great elation!! I had kicked drugs already about 1 1/2 years ago. Hope this is informative for you!
