Thanks for replying ! I've been taking 5HTP for a few days now, starting at a 100mg tablet, I'm now taking two a day. The brand I have are 'Healthspan Happy Days 5HTP Serotonin Tonic' (they also contain Vitamin C and some B vitamins), however I notice you are in the US, I'm in the UK.

I have noticed no particular change in appetite, my mood seems a little better, I'm still taking my prescription tablets on a lower dose. Strangely, my libido seems to have increased (I expected it to decrease). The only side effects are a gastric discomfort (constant indigestion, which could be partly down to the B vitamins) and very detailed and bizarre dreams, but not nightmares.
I certainly will continue to take them, 5HTP is not prescribed by doctors in the Uk at present. I hope you get the boost you need from a natural source such as 5HTP, I too have had some nightmare reactions to some anti-depressant medications. I seem particularly prone to the unpleasant side effects !
Good luck.

PS. If any can advise me, how long did you take 5HTP before noticing an improvement in mood ? Thanks !
