i prefer zanaflex 4mg tabs only for bad spasms, the capsules made me ill. but this will make me nap for an hour or two just like most muscle relaxers. i think soma works best if you dont want to nap right away. these days i dont need them daily so i might need to try something lighter like baclofen. if the spasms are not too bad i use valium and sometimes ativan works. i start with a half pill and i take more as needed.
