What dosage do you take? My doc started me at 10mg, and took me all the way up to 75 mg, taken at bedtime. I started having chest pains and rapid heartbeat at the 75mg dosage, so I went back to my previous dosage of 50mg. I was reading Dr. Don Goldenberg's book "Fibromyalgia" and he says he never gives patients more than 30mg of Amitriptyline. It seems like my doc is giving me an awfully high dosage, compared to that. So I wondered what dosage other FMS patients are taking?
