muscle spasm
"I've been on Zanaflex for over a month now and all I can say is it really makes me sleep well. I take pain medicines for chronic low back pain and also take sleep medicines to make me sleep because the pain gets worse at night keeping me up. I wasn't happy when they gave me this instead of Soma, because I had great results with Soma. Now I can say I'm glad I did go on this medicine. I take 2 about 45 minutes before I want to turn in for the night.  My spasms are relieved and I can sleep through most of the night and wake without any hangover effects. I'm glad I have this now."
