Tizanidine
"Tizanidine is an excellent muscle relaxer compared to ones like Flexerral, Robaxin, Baclofen, etc. Soma does work better but now it's hard to be Rxed because of FDA overregulating. Anyway, it helps me, gives me great sleep, and helps with headaches. The only side effect I get is dry mouth. Overall though, I highly recommend this over all the other ones our there! It's done an awesome job for muscle spasms."
