migraine
"I have suffered with constant daily headaches and frequent debilitating migraines for the past couple of years. In the beginning the only relief I could get was to go to the ER for IV medications. It was to the point where I was either constantly in bed in pain, or at the ER. Finally I was referred to a neurologist who started me on Zonisamide. That helped at first, but then the headaches became constant again. Also, I was losing too much weight on the zonisamide (I was already underweight and had trouble gaining). Finally, my neurologist switched me to gabapentin, and it has helped a lot. I still get some headaches, but they aren't as often or as severe. Side effect was some loss of balance and forgetfulness. And I'm finally gaining weight!"
