Ambien Cr 12 5 Mg and Ambien 10 Mg taken toghtgher yes?

No, that is too high of a dose to be safe. The Ambien CR releases half the dose when you take it, then the other half a few hours later to help you stay asleep. So you shouldn't add an Ambien 10 mg. to that. If the Ambien CR 12.5 mg is not working well enough, you should call your doctor about it and he or she can figure out something safe that will help.
