Could something else be causing the insomnia besides PCS ?? If you're routinely getting only a few hours of sleep each night there may possibly be something else causing it. Probably not, but just thought I'd throw it out there for contemplation.

Thyroid diseases can cause insomnia. I went 5-6 years undiagnosed with Hashimoto's disease (which doesn't always show on a standard thyroid panel but has to be specifically tested for).

I'm sure there are other ailments that can cause insomnia too.

It's kinda odd how PCS disrupts sleep patterns. My hubby (with PCS) never used to have trouble falling asleep and now (post PCS) he has to take medicine to get to sleep. Once asleep .... he'll sleep forever, I think.

Good luck to you. I know how debilitating it is to try to function with little sleep ---- add PCS on top of that and just the thought gives me the chills.
