migraine prevention
"Getting 100 units in 9 shots on my head wasn't a lot of fun. But I haven't had a headache since. It's only been 4 days, but my neck was sore today and I should have had a doozy of a headache. My eyelids drooped a little after the shots, but my wife didn't notice. I've got a good feeling about this. If I get through this weekend without pain, I'll be sold."
