I put myself on St. John's Wort last Nov has I had what I think was mild PND (didn't see a doc but was tearful/down/anxious etc). Have been taking it since and things have on the whole got better (may be the tablets, may be other things - who knows?) anyway last week we went away for a few days and I stopped taking it for four days - by day four I was starting to feel a bit anxious/down again - would stopping st. john's wort suddenly have this effect??. Thanks for any advice
