Gabapentin - 1800mg (600 3x a day). Been on it for 5 months. I don't think it's done much. Verapamil - 180mg (at night). Been on it for 3 months. I don't think it's done much. Propanalol - 40mg (at night) switched to Verapamil at the recommendation of another doctor so I didn't give it a fair trial. Nortriptylyne - 25mg (at night) tried it 3x and each time my ears rang really loud the next day so I stopped. Furosemide - 40mg (in morning) tried to 3-4 weeks. Might have helped a little. Prednisone - 6 day pack - felt better on day 2, improvements went away by day 3. Lexapro - 5mg - might have helped a little with my symptoms, or it just made me less anxious/depressed about them!
