I have been unable to drive on several occasions because my bipolar causes insomnia but unlike typical bipolar where being manic is energizing I find it difficult to focus and sometimes after being up for a couple days I don't feel alert enough to be on the highway.

Also some weird thing going on that might be metabolic that drops my blood pressure into the seventies and I get dizzy and can't drive then.

It's a pain in the butt for sure.
