muscle spasm
"I have been taking  this medicine for 22 years. I have Amyotrophic lateral sclerosis (ALS) and a very bad spine. I had a Doctor give me Tizanidine and it put me in the ICU. I almost died! 
After I got home and back on some solid food I took my two 750mg 3 times a day like I always did and they have been great for me. But the Fed. Gov. and DEA want to put their nose in sick peoples business and try to take all the things away that work for sick people. I really think they want us to die and get it over with.
This medicine my not be for some but we all have a different body."
