I Have Been On The Same Meds For Over 10

I have been on the same meds for over 10 years now, I'm trying to find a doctor in the Brandon area who accepts fl bc bs. I take 100 mgs. of ms contin 2 timese per day and and 30 mgs of oxycodone 4 times per day. but everyone wants me to try something different. I am comfortable with what I take . no side effects
