muscle spasm
"I must be one of the rare ones.This medication was to be a resolution to constant pain from a pulled muscle in my face and neck after oral surgery. I was instructed to take 1-5MG tablet twice daily for 1 month. I take it 2 hours before bed, and by bedtime, I'm so wired and jittery, I have to stay up to avoid keeping my spouse up.  I also have restless leg syndrome, spells were rare until this. After taking 1 tablet, I will spend the next 4 to 6 hours, pacing, as it seems to cause prolonged restless leg syndrome spells. The feeling seems to affect my arms as well, so I have this need to shake my hands/arms violently. Now, completely exhausted, I have to fight through the pain in my face still to sleep. I no longer take it."
