I am taking 5-HTP to help me with sleeping. My 16 yr old daughter is also taking it to help with stress and weight control as well as sleeping. We have found it has helped a lot and I don't have to take it every day . My kids call them the turkey pills because the amino acid they contain are the same as the one found in turkey, milk, bananas etc. We both take 100 or 200 mg a day.
