I hate to say it because they are jerking you around in general, but they are probably right about the partial fill. I'm not sure what schedule drug kadian is, but I used to work at a pharmacy and it was against the law to give partial fills of the stronger meds. No idea why, seems stupid to me, but..whatever.

I know its not fair, but I'd be calling around to other pharmacies to see who could fill my script. Then I'd let CVS know.

I hope you are able to get it ASAP.
