Allthough some doctors have become EXTREMELY careful when it comes to giving out oxy's because of all the media attention from overdoses and the FDA cracking down on dr's who give out oxy scripts like candy........so it may be hard to convince him to up your dose....but since youve been on it for a year, your tolerance would obviously have increased and it would only make sense for him to increase your dosage. His ony other option would be to put you on a different drug. In this case, give it a try, but then tell him after about a week or two that its still not helping and he will more than likely up your oxy dose. That way he can atleast say that he tried other alternatives before just giving you more narcotics.
