Muscle Spasm
"I&#039;ve only been on the medication for a as days but it&#039;s the first time in years that I haven&#039;t had that seized knots in my back . So I am fairly happy with the medication despite the drowsiness its causing.  I hope that in a few weeks the drowsiness will go away. At least it doesn&#039;t knock me out like Rosario or tizinadine does."
