Muscle Spasm
"I take this medication for severe abdominal pain associated with IBS. It&#039;s the best medication I have found in terms of controlling the pain, and works even better than painkillers. However, like others have noted, it makes me VERY drowsy and just gives me an &quot;out of it&quot; feeling even after it wears off. I would definitely not recommend taking it if you have to drive, take a test - really anything but the most basic physical and cognitive functions are impaired."
