DR TomofOz: A headache is an annoyance, an inconvenience and a bummer, but one can function if one must with a headache.
For me, migraine -- which I suffered one or two times a year when was very young, and which I've suffered maybe four times as an adult, thank goodness -- afflicts me with pain so severe I can barely lift my head, I can barely see so sensitive do I become to light, and makes me extremely nauseous. The quicker I can be knocked out the better. Mine have never lasted more than 18 hours, but recuperation can take several days getting back up to speed.
