Wise advice to limit yourself to one card, even without this stupid disorder. My mania has always been pretty mild (hypomania) but it's very clear to me now that I would always abuse credit when it was available to me, and always told myself I would pay everything off, so what was the big deal. The temptation, in my case, was to mood alter by giving myself (and others) stuff I couldn't otherwise afford. Probably classic and common as dirt, and that's likely one of the things the banks count on... people like to SPEND. Even if you feel you could stay smart about it, don't temp yourself because as you already know, the moods are unpredictable and easy to get swept up in it all... yes?
