For me, the line from hypomania to mania is crossed when I finally lose all rational thought and restraint in my actions. In hypomania, I can be hypersexual, but not cheat on my spouse. I will want to dance, but tend to stay out of the rain. When manic, I will dance in the rain and am at risk of cheating on my husband (not something I'm at all proud of). When I'm hypomanic, I get hyperreligious and will read and pray and meditate for long periods of time. When I'm manic, God calls me on the phone and all the answers of the Universe are suddenly crystal clear. I tend to get at least a few hours of sleep when hypomanic. When I'm manic, one hour a night will be enough, if that. My thoughts become too fast and I feel out of breath just sitting still, like there's something inherently revving inside me. When hypomanic, I get a lot accomplished. My brain is firing on all cylinders and ideas come quickly and easily. When manic, I can't focus and nothing gets done.

Does that help any?
