I was awakened at 1:30 one morning, (before I learned about drinking a couple of gallons of water a day) with the beginning of a CH. I got out of bed, turned on the shower, full cold, and put my head into the cold water. My scalp tingled and the headache left, immediately. Since then it's worked about half the time for me.
It is not pleasant, but when it aborts a CH it's well worth it. However, when it doesn't work, you're cold wet and your head hurts like hell (and you'll be saying "If I ever get my hands on Phil, I'll..." :)
Hope this helps someone.
