What Dee said.
Your sponsor is not a doctor.
Tell your doctor about your addiction(s) and let them take it from there.
My sponsor had neck surgery and shares over and over about how she did not take pain meds. That is great for her, but if I am in severe pain as a result of surgery and the doctor knows I am an alcoholic and prescribes pain meds, I am going to take them IF I need to. Not for a buzz.
If I was worried, I would put them in the hands of a friend to administer to me.
