Hello. My Boyfriend Is In A Treatment Facility That Gives

Hello. My boyfriend is in a treatment facility that gives him buprenophine. He's shown a great deal of progress and is now leading a normal life. However, I guess due to insurance related purposes, his current doctor is now saying as of his next apt he is going to switch him to suboxone. My boyfriend says he's tried that before and it didn't work for him. He's even told his dr that,but the doctor really didn't seem to care. I want this treatment to assure that he's not out on the street again looking for drugs because he had something he liked that worked for him, but now that's about to change. What should we do? He's not going to take the suboxone.
