If I were you, I wouldn't give up yet. As MM said, it can take years to find the right combo of meds and dosages. I would strongly caution against herbals as a front-line approach, as the evidence based proof just isn't there. You could certainly try herbal supplementation, but get your psychiatrist's clearance on anything you want to try. There could be interactions or other side effects which would only complicate his ability to nail down the right treatment.

Unfortunately for us with BP, the only method of getting to the right medication combo is trial and error. It can be disheartening at times, but if it helps at all to know, there are a lot of people going through the same difficulties. Take heart and carry on. If only a few meds have been tried, know that there are tens or hundreds more out there. Best of luck to you.
