It is quite common to have to try many different meds and combinations of meds until you find what works for you. Yes, it can be confusing and frustrating. I hate to think of how many different drugs I have tried. I've had the same mix now since July 2011 although the dosage has changed. I also have had intermittent ECT since then. Right now it is at every two weeks. For a long time it was only once a month. But, I had a breakthrough episode and we did another series of 6 and back to every other week. Don't let this worry you. Not that many people with bipolar end up on ECT but for me it has been very helpful.
