Muscle Spasm
"I have chronic pain from several herniated discs and  spinal stenosis. I also have fibromyalgia. I began taking Zanaflex last month and the relief is wonderful. I no longer hurt and spasm all night and now I can sleep instead. I take 4mg tabs 2 at bedtime and go immediately to bed as it makes me drowsy right away and I become dizzy if I stay up. I wake up rested with no hangover at all and feel good the next day. I take narcotics during the day for pain relief and the addition of this to my regimen is great. I love it."
