I am glad you are talking things out with your physician. I know Valium can be addicting if you take it over a long period of time. IMHO it is the better choice if you are looking for the muscle spasm relief. Be care thow, as you are on a narcotic T3 with codeine...............be sure you discuss with your physician re mixing them all togehter.
He is right, most MDs won't prescribe more than one benzo.
I hope your feeling better soon.
