migraine prevention
"Tried this medication for prevention of migraines. I developed severe numbness in my hands and feet and unrelenting pain in my arms. I also had huge problems thinking at a normal speed. Took it for 3 months thinking well I'll adapt and the side effects will lessen or go away. Nope. Didn't help decrease the frequency of my migraines either. I was very surprised at the side effects as I usually don't have any sensitivities to medicines. Hope your experience is better."
