I've read the dosage info in the library.....but just curious "how" to do this. Do I alternate the two, every couple of hours or so ? I'll be 5 weeks out tomorrow, still taking more Norco than this "stubborn" Bohemian had planned.......just curious ! Done with out-patient PT, now just on a home program. Santa brought me a new recumbent stationary bike, so I'm happy about that. Go back to work in a couple of weeks. Doing good, just tired of the nagging ache....but I know it will go away in time.
