Bit of vertigo

I can get it when I'm very tired. Time to go to bed.

edit: enough to wake me up. Positional vertigo, worse when lying down, so positional. A few years ago I was diagnosed with benign positional vertigo. Today seems to be milder than when I initially had it. I've had mild bouts before. I may have to sleep sitting up tonight. It's upsetting and annoying, and strongly gets my anxiety going.
