I have rapid cycling and lost of mixed states. My cycle is 3-7 days for either depression or hypomania with a mixed phase of 1-3 days in between. I never have "normal" times. Those don't exist. I'm like a pendulum, constantly swinging...
Insomnia.... it comes and goes, I actually regularly get about 7 hours at least. Yes, I can have hypomania without it. My hypomania is dysphoric. But, I do have the "sleep with no rest" problem. I'm asleep but my brain isn't sleeping, or something.
However, if I do have insomnia or my sleep schedule is disrupted, it's very bad. My mood and cognition goes off the charts and easily I can have a full episode in those cases.
