This is the "wake up at 2 am" kind of insomnia. Usually very irritating since I get up at 4:00 am on weekdays, so it soon becomes pointless to go back to sleep. On weekends it is less of an inconvenience, but I'm (planning to) get up at 6:00 am today so still irritating.

I very seldom have the "can't fall asleep" sort of insomnia. I'm usually out like a light.

I wish I understood why I wake up in the middle of the night, and could stop it.
