Hi Kim, I just wanted to let you know, I was on zanaflex too but had to go off of it. I had blood work done and being on zanaflex at the same time made my liver count really high, it was doing damage to my liver. Otherwise the drug is really good. Just be careful, it says that it effects a certain percentage of people so it might not do anything to you. I research everything that I take along with all my blood work. The doctor should order you blood work to make sure that Zanaflex doesn't harm your liver or kidneys, etc.
