I didn't see anyone mentioning that it can be very moreish for some people.
Not lasting "long enough" and making you keep popping more till they're gone.
I hated them when I had access to them (for that reason).
I know lorne said not to mess with other muscle relaxers than this (crisoprodol, Soma)
I find baclofen better than soma.
As far as another one that is worth TRYING is tizanadine (Zanaflex).. had an rx for those a while ago for a long time, never lost effectiveness for its needed use (muscle relaxation) its comparable to clonidine i suppose. So i guess personal preference would apply.
So basically MR's in order of recreation IMO/IME: Baclofen, Carisoprodol, Tizanadine.
(This isn't counting the muscle relaxing benzodiazepines of course lol).
Just my .02
