Anyone ever try plan aspirin??

I read somewhere that taking one or two aspirin seven to ten days before going to altitude will help you from getting headaches by thinning your blood a bit. I live at 250 ft and am prone to headaches the first couple of days above 6,000 ft. I took one aspirin a day for ten days before doing Kings Peak. I landed in Salt Lake in the afternoon, hiked to just below Gunsight Pass the next day, then on up to 13,528 the next morning with out ever having a headache. Made a believer out of me.
