muscle spasm
"Unless you have MS or are in DIRE need of spasticity reduction, i would recommend no one take this stuff. It is a nasty, nasty, nasty drug, made me feel out of it, slurred speech. It also caused me to develop sleep apnea, and it also increased my anxiety. It also makes it hard to breathe when laying down. Weaning off of it was awful, wave after wave of anxiety and then aggression.  I'd rather have back spasms then feel the way it did. I weaned totally off it 48 hrs ago and I've had hiccups for 14 hrs and some agitation."
