I'll have to agree with Rhapsody. It's best to get a "real" medication. The 2 mentioned, have had reverse effects, and without any documented research like "real" meds. makes it harder to help someone self medicating. Use caution with these "OTC" remedies, always check with a doctor. Sam-e is not good for bipolar disorder, some literature even states that and cautions people with psychiatric disorders to check with their docs before using.
We had a friend, whose dad's wife swore garlic pills were the answer to her husband's high blood pressure, without the right meds this man had a stroke, almost died. There are other stories I have heard, and would hate for anyone to have to experience them. Just my 2 cents.
