Tegretol is a mood stabilizer, so it is natural that you would have manic/hypo episodes when the dose is lowered. Perhaps you are going too fast? Try going to 150 and see how that goes. (200 one day 100 the next), then try lowering it to 100. Otherwise, you may find yourself with a lot more art supplies than you need. (in which case, mail them here. We can use them for school.)
