muscle spasm
"I have been on Zanaflex for about a month now.  I have tried many muscle relaxers that have NOT worked at all.  I take 4mg 3 times a day.  It is a lot better than other medications I have been on, flexerol didn't do anything at all, and Soma just made me totally loopy.  Zanaflex relaxes me so well while still allowing me to operate regularly.  I highly recommend this medicine, and for those who are just starting this be careful when driving on this.  For the first week I only took it before bed time, then on a day off work I took it shortly after waking up and noticed it didn't have any major effects on me except calming my back and neck spasms."
