Night Owl

I've always had pretty bad insomnia. But over the last couple of weeks, it's gotten worse and worse. I've pretty much been functioning on about 4 hours of sleep a night. I thought that eventually I'd *have* to sleep because my body would be so exhausted, but no such luck. My body just won't rest. And I can't turn my brain off. A month or two ago, I thought that I had just the right combo of sleep aids to get to sleep at a reasonable time, and get a good night's rest. But now, nothing seems to work. Not soothing music, not white noise, not NO noise. Not laying in bed for an hour, not moving to the couch, not turning on mindless TV. I try reading, knitting, writing... nothing works. Not sure what else to do. I give up.
