My own tolerance -- and even enjoyment of -- commotion waxes and wanes with my bp cycles. My boss is always criticizing my inability to "multi-task," but I must confess, I do find doing this bloody well impossible while in a depressive cycle. On the other hand, a hypomanic cycle tends to make me seek out as many sensory stimuli as possible at once. With my bp, I'm more often on the "down" lift than the "up" one, so I could see commotion becoming a problem for someone with bp (and there's never been any real disagreement about my dx, despite the fact that I've seen many docs and Ts). Just my two cents. Ta. Cheshire Cat
