Mine is the same way! At first he gave me a diagnosis of BP-NOS (a wastebasket dx if I ever heard one!) and depression; the depression dx went away last summer when he first saw me in a hypomanic state. BP-NOS stayed around until I finally asked him at the last visit what the hell kind of bipolar I really am. He said that the "diagnosis" part was actually more about how insurance companies pay doctors for their services, and hemmed and hawed for a bit: "welllllllllll......"

He still wanted to stick with NOS because I apparently don't fit into any neat little pigeon-hole, but admitted he doesn't like making a definitive dx anyway. He finally conceded that I'm somewhere between 1 and 2, but he leans toward 2 because the only manic/psychotic episode I've ever had occurred when I was on Wellbutrin a couple of years ago. However, he won't rule out BP 1 either........and round and round it goes. Maybe I'll never know!
