Guess who was woken up by a horrible sinus migraine?
Me! Err, wait...

I've taken to using a neti pot every morning, which doesn't really get into the sinuses but at least clears the gunk away from where they drain. Usually this plus a hot shower brings a normal headache down to background levels.

On the nausea-inducing migraine days, though, I just lie in bed until it goes away enough to get up - can't sleep, but pretty much anything else just makes things worse.
