Hi JohnShaft,
I tried St John's Wort while I was struggling and found that I seemed to get more wobbly, like it was doing something with the depression but not what I had hoped for.
Like you I have hung on without prescription drugs for whatever reason, and found that I got through it anyway.
The Psychiatrist I saw back then was pretty impatient with me and said "You don't even know what it is to feel normal". I still didn't take the Prozac. That's just me, I'm not giving any advice here.
Good luck, and let us know how it goes.
Cheers, Myzen
