I was put on 20 mg twice a day to combat my Crohn's Disease. A few days in, I began having trouble sleeping because of a heart beat that was making my whole torso and head throb. Exactly one week in, I woke up with a bad headache and nausea. I got out of bed and my heart started racing. I couldn't take my pulse at the time, but my estimate is about 150 beats/minute. The doctor accelerated my tapering in response to this episode. Right now I am taking 30 mg a day, but I still experience a heart rate in the 130's and chest pain several times a day unrelated to physical activity. I will say, however, that all the symptoms of my Crohn's Disease have really been diminished by this drug, and so far I am willing to accept these side effects.
