Prayer request: My health

I have to get up in about 6 hours, to make a trip out of the country, and I feel wretched -- something's been trying to get me for a couple weeks and my body's been fighting hard to keep it away, but not getting enough sleep to aid the fighting. Anyway, I'll survive, physically (although more prayers for healing and strength would be appreciated, in light of next week's English teaching camp), but what happens when I'm unwell is that my logic and common sense (which I already don't really possess :D) take a nosedive, which isn't very helpful when you're traveling and need to be alert. :) Thaaanks for prayers!
