muscle spasm
"I have been on xanaflex 4mg 3x a day that I take at night ti help me sleep. It helps the muscle spasms in my legs and allows me to sleep. The only problem I have is that it only lasts 4 hours and then I wake up. Works best if you take thr xanaflex, wait 30 minutes and then eat something and the xanaflex will work that much better."
