while i can understand where you are coming from here and the fears that just come along with having to be on any form of narcotic therepy, there were some errors here that simply could have been prevented if you had done just ONE thing. informed your PM BEFORE doing this. i am in pain management too and do have a past history of actual med abuse back in the 80s to boot. the one thing you just ALWAYS have to do when it comes to those meds even being rxed by your PM, is to just keep them as informed as possible about ANYTHING related to them. they simply really don't know why there were not meds in your system, only what you TOLD them, you know what i mean? for all they know, you either took them all way too soon or from the DEAs point of view(they just DO weigh very heavily in PM) you could have diverted them and sold them for money.
trust me, they ahve heard sooo many different stories over the years when it comes to meds that they just pretty much blkow things off if things don't appear 'right" in anyones case. did you actually sign a contract with these people when you started or thereafter? if you did,EVERYTNING that you have to follow is simply covered in that contract. if ANY rules are broken, it IS just grounds for dismissal. the bigger issue here is not having the meds to actually show that you had them, you simply "chose' not to take them, that was your 'proof' right there, ya know? if you had simply informed your PM as to what you did two times a year they would NOT have rxed them to you. according to THEM, you should simply have alot of extra meds. you just should have kept your "proof' just incase.
i really do think your only hope here since this has been a very long term type of relationship,would be to just be completley and totally honest about all this and tell them anything you can to try and justify your errors, to just to try and get that second chance with them. that of course is going to totally depend upon your actual level of pain, condition and whether or not you have had any reasons in the past where they could have doubted you or your actions when it came to the narcotics at all.
i do wish i had better info/news for you here, but just even being in a pain management program at all is a whole different world than simply seeing like your primary and having them just write a narcotic rx. totally different. the very strict guidance/direction and demanded compliance in every way shape and form are there for very specific reasons. to protect them and the patient. hopefully you can make them understand here. but if you can't, hopefully you can find another PM that will continue your therepy. you just really kind of did this to yourself when you failed to let your PM in on what you were simply doing with the meds that THEY rxed to you. hanging onto the meds that you just did NOT take would have helped tons in proving you simply did not actually take them, ya know? it is just one of those very hard lessons learned along the way. at least you know now that you just HAVE to keep your PM in the loop with anything related to the narcotics they rx you. sorry it turned out that way. i do wish you luck with this and please let me know how you are doing.
