Hi I Am A 57 Yr Old Female 112 Lbs

Hi I am a 57 yr old female 112 lbs 5 ft tall was diagnosed wh diverlulites (sp) aprox 19 yrs ago resulting from a mistake during an operation to remove cyst from overie and my bowel was cut. Spent a month in hospital and have been taking t3 ever since. They no longer control the pain but am concerned about opiate abuse that is all the news now. 30 t3 lasts aprox 2 and half months. Is there something stronger that I could use, I would like to point out that I sometimes can go days without any pain meds,so I am not to concerned about the abuse part as more as how this will affect my body later on in life? I do plan on living a long time lol Thank you Donna
