I took 5-htp for 2 years on and off
IMO it is effective for only mild depression
It gave me a sense of contentment. I took different brands, "Nature's Sunshine", and Natrol (i think it was)... I finally settled on Natrol 200mg, taken 1x, and I took it nightly with ambien. I would have some crazy dreams if I had been off of the 5-htp for awhile.
5-htp may be worth a shot for some people, but if you've made it this far in your quest to get better.. you should see a Dr. and I'm guessing there aren't too many Doctors out there who would recommend this product to anyone.
