muscle spasm
"Seems that with the first dose I was feeling much better, in fact I didn't have any pain or spasms for a few days, I thought to myself, "wow this actually works." Low and behold a week later after starting the script I can't sleep, I toss and turn, and feel like I am half awake and half asleep. My mouth gets so dry and my teeth hurt to the point of serious discomfort. The migraines are probably the worst though. I just can't imagine that this drug is doing all of this but it seems as though I need a different prescription."
