Migraine Prevention
"The first 2/3 days were very encouraging. It helped me a lot. but afterwards I had severe side effects, chronic diarrhea, vomiting, nausea etc. generally feeling really crap, so that i had to stay home for a couple of days. Even a reduction in dosage didn&#039;t help much. switched to verapamil, which works similarly, but practically without side effects for me."
