muscle spasm
"The doctor put me on this medicine a couple of weeks ago. They seem to help with my muscle tightness in my back, but makes me very sleepy so I can't really take during the day. I take it about 30 mins to a hr before bed and sleep good, but they give me very disturbing, scary dreams. I thought maybe it was from the other medicines I take, but apparently I'm not the only one who has bad dreams when taken."
