I don't remember the dosage because it was a few years ago, but I got body tremors and twitches. It started with my limbs and worked it's way into my face and torso. It eventually became painful and I had trouble breathing. So I went to an urgent care place and they took me off it and gave me a benadryl shot and pills to take home to take ever few hours to help with the shaking, surprisingly it did help and it stopped hurting as much. Within a few weeks the shaking completely stopped and I never went back on it again. It's been brought up by my new pdoc a few times and I've refused to take it again.
