I used flexeril - which wasn't bad - but zanflex is better. But it does make me sleepy (so did flexieril, but not as much - I took 10, 20 mgs).For day I use methocarbamol which does not make me tired.

I also use potassium and magnesium supps, heat and rest. Stretching - when I'm already spasming -only makes it worse. I do yoga when I'm not bad, and that keeps me not bad.

For me, it's the whole regime that seems to work. One or the other alone is not enough.

Swimming is really a good thing though and if I could only pick one thing that would be it.

(Just so you know, I did not wait for the bloodwork to start the supps, and my docs never had a problem with that. I don't see how they can hurt if you use as directed)

Hope you get relief soon.
