I think I must be one of the BPs that the doc is talking about. I'm on Lamictal and a small dosage AD....I cannot tell you what my life was like before these meds. I had talked to medical docs for years.....asking for something else to help me and they poo-pooed me.....now I went to a psychiatrist and the first thing she said was she wanted to do something differently. About three or four times yearly, I get so low that I scare all around me. My mood now is "normal" and I feel so much better. My dose of Lamictal is very small and I am so thankful that I am taking it. I found the information that the doctor posted to be extremely interesting. Thanks.....Pat
