Re: 5HTP side effects?
I am going to try and make a long response, short...
My husband went to a fantastic rehab that handled both mind and body for recovery... Group therapy, Individual counseling, NA meetings, AA meetings, life skills, and Nutrients. He takes 5HTP in addition to a number of other nutrients (like Amino acids, fish oils, etc.) and has been doing amazing well. None of the side effects that you have mentioned (He has been on these nutrients for almost 90 days), but the difference is that a Dr. has gone over all of this with him (blood work, hair samples taken, etc.) so you may not be taking the right amounts. Also, I do think you need to be consistent with taking it every day. I hope I have been helpful. PM me if you want some info on the Dr, rehab or the website...
