migraine
"I'm taking Neurontin for my Basilar Migraines. I started out with 600 mg/day and it worked well in controlling my terrible auras (vertigo and double vision) for about 10 months. I started experiencing mild vertigo the past 3 days so it was increased today to 1200 mg/day. Hopefully it will continue to keep my auras in check. 

For me, the downside of this medicine is feeling lightheaded and I sometime have trouble recalling things. Also, sometimes I get a "high" feeling, but it's all good."
