There's not really a whole lot of "normal" in bipolar. I saw someone else here said a while ago that there are as many types of bipolar as there are people diagnosed with it. I denied mine for years because I thought I was "just" depressed and had never had a real manic episode. Now I look back with hindsight and see what was probably many hypomanic episodes. Just came off what I think was my first major mania and wow, that was a ride, and not a good one. Read through some more reference material on BP and took a hard look at lists of symptoms and the DSM-IV diagnostic criteria for mania and depression, and it's all right there. BP I for sure, and sex drive and sexual behaviors are listed symptoms. I should probably apologize to my pdoc for doubting my diagnosis, she had it right a long time ago.
