If you go to the hospital they should help you. My friend is still recovering from a anterior/posterior spinal fusion and his surgeon was being a real asshole, they would schedule his appts beyond the 30 day script and crap like that, he had to argue to get pain meds after this surgeon did major major shit to him...needles to say, he doesn't see him anymore. But anyway, he went to the hospital because he was out of medicine and explained when his appt was and they gave him med in the ER room and then sent him home w/ Vicodin 10's, now I now you are on methadone and they should have no problem giving you enough to hold you over...do you have an empty bottle you can bring? I highly suggest bringing an empty bottle w/ a very recent date on it.
