Blaahhhhh. After six hours of absolutely sound, deep sleep, got woken this morning by a headache. Within the hour, it it had grown into M I G R AI N E. The iron-band-around-the skull type, with added nausea and balance problems (an odd feeling that my feet were higher than my head, even when I was sitting up).
Better now, still wobbly and headachy. But no more experiments with meds. Looks like I’m hooked on the dammed things for life.
