Sleep is a weird thing for me. Even my pdoc and t don't understand my sleep patterns. If I get 3 to 4 hours a night, I stay pretty normal. Well, at least normal for me. But if I start sleeping more than 5 hours a night, for several nights, it will trigger a depressive episode. Now, when I'm starting to get hypo, I'll get may 1 or 2 hours of sleep, usually interrupted w/ majorly weird dreams. I have gone several days w/ no sleep, which is never good.
