Was barreling along doing the Sat. aft chores when I get me one of my migraine auras. This one didn't evolve into anything severe pain-wise but it sure fuzzed up the thought processes. I get that short circuited feeling whether the headache is mild or severe. Everything will be now off-kilter for a day or so. Has almost a derealization sort of effect. So anyway the day effectively ground to a halt. Focus done died.
