I just began taking Darvocet again after taking Ultracet for a week. The ultracet helped my pain slightly but made me extremely nauseous.

I hated it. I had always taken hydro but pm dr is new so I can respect his "hierarchy" of drugs to try until he gets to know my case better. The darvocet is helping me much more than the ultracet. I have been off hydro for only over a week now (i think) and I'd been on that for over a year. So I guess it just depends on the person. Maybe you should explain to your dr that it's not helping you at all. Good luck. I really can feel your pain. The darn ultracet was useless.
Okey
