migraine prevention
"40+ years of migraines, foods, weather, you name it, day after day.  Pills, ER, you name it.  Finally tried Botox.. Didn't notice improvement first two cycles.  Wits end.  Started to help a little on 3rd, then wore off after two months.  This time, full 200 units, no migraine for over a week so far.. That's miraculous!"
