Have been on it for 15+ years- it is an awful drug, but I'm in the select few that tolerates it well.

I also cannot feel my extremities at times, cannot gain weight to the point some have accused me of having worms, and appear drunk occasionally, even when stone cold sober.

Still a better alternative to life without Topomax.

EDIT: epilepsy and cluster headache issues- wouldn't suggest for migraines- ever.
