The only way your family member is going to tell you no is if you tell her to tell you no, like Dee said. For the future pain pills you get for the future dental work the only thing I cold recommend is to give them to someone you trust. You're also going to have to tell them that you have a history of abusing them and that they can only give you the rx'd amount. Your sobriety is your responsibility, no one else's. So seek out other help, like a recovery program. Once the addiction has been started its very difficult to beat, especially on your own. You will need help doing this, we're here for you, but trust me when I say that SR alone will not keep you sober.
