I rapid cycle as well... my are typically daily though .... rarely do I cycle within the same day, but it has happened. It sucks not knowing who I'm going to be when I wake up, or even when I get home from work, or ever.

My old p-doc has me on Lithium and Trileptal.. which aren't helping at all... but I go to a new p-doc in a few hours to get my meds re-evaled ... my primary care doc doesn't like the side effects i'm getting from the lithium (really low thyroid levels n stuff). So maybe this new p-doc will give me something to help the rapid cycling. *crosses fingers*
