Zanaflex vs baclofen. does any have experience with zanaflex

my current neuro put me on zanaflex and wrote me a script for baclofen (which i didnt fill) im supposed to take both but im not sure if thats a good idea i dont want to be a zombie i just want less pain. to my understanding they are both muscle relaxers. so i dont understand why a doc would put me on 2 muscle relaxers at the same time. isnt lthat over kill? BTW the zanaflex does seem to work better than the baclofen. so what is difference between the two?
