Lets say 3 hours sleep is that Insomnia? Some say yes some that's all they need. Myself I can only sleep 3-4 hours a time then up a couple then back for another 3 or so, I consider myself a Insomniac. However there used to be bench that posted here said he only slept 2 hours a night and was fine. I can't remember the last time I slept straight 8. No damn wonder I'm tired all the time.
