I suffered with severe depression. I went through a whole lot of prescription antidepressants, the side effects were to much for me so I also wanted to switch to something natural. I tried SJW but had an allergic reaction to it, so then I tried 5htp. I felt better the first day I took 5htp. I continued to take it for 2 years, along with therapy, exercise, prayer, meditation, reading books about depression, and listening to uplifting music. For the most part I'm cured, and now when I feel "it" coming on I have the resources to stop "it".

Here is a website with more info, and dosing guidlines on 5htp.

Wean yourself off of the prozac slowly and expect to go through withdrawals.
