Ok, what can I do to make my head feel better? All day today I've not eaten, just drinking clear liquids, and I have one H*LL of a headache. Tomorrow is my colonoscopy (Ahhhhhhhhhhhh) and I'll be glad when it's over. I'm being good to myself and it's the last round of my physical. My mother died of colon cancer a few years ago and I've yet to have one (shame on me..). Anyway, I thought someone might have a cure that doesn't involve eating something.
