I don't want to give up all my pain pills for rehab. I might have trouble getting a refill if I have real pain later.?

Are you addicted. Once you are in a rehab setting you will be medically monitored. If pain medication is necessary it will be administered by the staff there as long as you are in treatment. People sometimes have dual addictions, so if you are in treatment for alcohol, there is no point not being treated for pain pill addiction. If you are only addicted to alcohol, you will be treated for that.
