Why are you starting Wellbutrin by yourself without your doctor knowing and prescribing it? It sounds like they don't want to prescribe it if that's how you're going about getting it, I know it has less a chance of causing mania usually but still can cause it very badly in some people. I'm sure they have a good reason and your best interest at heart, I've seen a lot of your posts all I can say is you should stop messing with your medicine so often without consulting your doctor. A lot of the instability could be due to all constant switching, stopping, increasing, and lowering you're doing.
