IIH and sleep

So, I don't know if anyone else experiences their symptoms the way I do, but I really don't know how my IIH responds to sleep anymore.

At first I thought that logically, less sleep = worse symptoms and if it gets really bad, a flare up. But sometimes I sleep only VERY little (talking 4-6 hours max), and I feel the best I ever have (considering that I'm still chronically ill of course)?

The concentration issues on Topamax get worse either way for obvious reasons because my body is not immune to the side effects of being in a sleep deficit, but today for example, I had approximately 5 hours of sleep and didn't get a tension headache during the entire day - not to mention that I could move around in whatever way I pleased while I honestly expected to be borderline bedridden.
