Yeah, I recently had a hypomanic episode where I spent way too much money (in the thousands of $) in the span of about 1-2 weeks. I was getting a normal amount of sleep the whole time, but I did have lots of wake ups in the middle of the night.
My therapist wondered if I was actually manic rather than hypomanic, but I guess it is hard to draw the line between the two categories sometimes. I normally do not sleep much with manic, though... but if this last episode was anything to go by, then apparently I can get like 7-8 hours and be hypomanic, at the very least. I did crash into a depression as well.
I am a mix of all sorts of crazy sometimes with on and off psychosis, so I can never tell for sure. It's too complex for me.
