migraine prevention
"First  week ok.  Dizzy first day.  Overwhelming sense of wellness for the first week, minus dizzy feeling. I thought this is great.  

When I increased the dose as prescribed the second week I developed a headache the next day. Had pains in my abdomen, all throughout my back. Continued for 2 more weeks then my body shut down, had the worst migraine that lasted 2 days. I slept for 4 days. Then muscle weekness, nausea, and persistent headache. My bladder was painful and felt like I could not empty it. Three days off them, I can finally stand up straight, but I lost a week of work.

Might have been ok if dose was not increased."
