Zanaflex rocks! it is short lived, and works great on those stubborn spasms. it will take a few days to really sink in and work. soak in a nice warm bath, and practice some yoga relaxation before you go to bed.
dont take Cipro while on Zanaflex, or at least let someone know you are on it. Cipro can cause the zanaflex to be more powerful, and cause the liver to work harder to clear it from the body.
I hope you slept better last night.
