Muscle Spasm
"I have taken many muscle relaxers over the years. After reading some of these reviews I thought I would share my experience. 

I suffer from fibromyalgia, degenerative disc disease, sciatica, myofacial pain with trigger points...I think you get my drift. 

This has been the only muscle relaxer I have not become immune to and that works for me well. I generally have major side effects from medication, but I do not feel anything has been noteworthy with this muscle relaxer.

My suggestion would be talk to your doctor, give it a try. ANY medication can have adverse effects or not work for you. Each person is different. If people are taking other medication in conjunction to this then it may effect them differently."
