No Zzzzz

Maybe it's the prednisone (though the dosage is really low), but more likely it's the 9 channels of static that are competing for attention in my head. Tim went to sleep around 12:30 last night, and I said I'd be up soon. We used to almost never go to bed at different times, but my sleep schedule is just messed. up. lately. (OK, that's not totally true. At all. For several years I've woken up almost every night in the middle of the night for at least an hour, but I never had trouble falling asleep, or waking up more than once.) 

I stayed downstairs staring at How Do I Look? on TV and listlessly clicking things on my laptop to see what I'm behind on and/or on top of, wedding-wise. Emailed a few people. Facebooked. Then I trudged upstairs, "read" some US Weekly (I swear I'm not as vacuous as this paragraph is making me sound), and tried to sleep. Woke up at 4 to go to the bathroom. Woke up again at 7 and came downstairs to do the same crap on my computer. Still here. Still tired. Still want to sleep more. (9:15 AM... ahem... yeah, musicians' schedules are a little different from normal people's.) 

But my brain is going apeshit. I know it's because of the wedding, and I know I should shut the stupid computer... I just can't seem to make myself do it. Will it be better once I'm so exhausted I have no choice but to sleep, or am I not going to be able to press pause on the brain drool until October 27?

Any of you have chronic insomnia? Advice?
