When I used to have that problem I was prescribed Klonapin (Clonazepam). My hands and feet would violently twitch from time to time and my hands would always be shaking. Really interfered with sleep! See if you can give it a shot though. And don't be scared, the dyskinesia is a common side effect to many migraine medications and rarely something to worry about.
