Can you take ambien and muscle spasm medicine together?

The should be perfectly fine. In fact, my dad who broke his back a couple years ago was forced to take a number of things in order to go to sleep after his surgery. These included AmbienCR, Percocet, and a muscle relaxant. (and maybe a little pot too. haha)
He got more messed up from the pain killers than anything else. Just dont mix these with alcohol.

I have taken AmbienCR with muscles relaxers together too, but it may depend on which muscle relaxer you are taking.
