Important question about St. John's Wort!!!

I’ve been taking St. John’s Wort since Thanksgiving last year, and I’ve had great results with it… until I became horribly photosensitive about four weeks ago (that’s a known side effect of SJW, but until an awful attack of poison ivy, I really hadn’t noticed it.) I dropped the SJW 10 days ago; however, the photosensitivity really hasn’t gone away yet. I kinda think it’s improving, but… How long would it take for this side effect to go away? As long as it took the original medication to take effect in the first place? On a larger scale, how long does it tend to take the side effects of ANY herbal medication to go away?

And if nobody knows the answer here, maybe somebody could suggest an appropriate board/discussion group/whatever somewhere else where somebody might know? I really, really, really, really want to find out the answer!!
