Interesting the effects this had on you. I had been on ZOloft for 10years and seemsed after 5 years use, I was not getting the same happy, calm feelings and stress intolerance getting worse too ( but also sttributing to the worsening of my AF state.
I am going to give L-Tryptophan another shot, but with Doctor's Best Enhanced with B6 and niacinamide. L-Tryptophan needs these B's to help it cross the blood-brain barrier. It's supposed to help create one's own seratonin. I did 5-HTP for a few months over a year ago and worked semi ok for deression and anxiety, than only lasted for a few months.
