My sister also told me she was taking codeine last week. Luckily she is aware of the problems this too can cause. Hopefully she hasn’t swapped one for the other.
Great news about your mums 20 year anniversary. I did go to an AA open meeting with my sister and she was the youngest there. When I made her go she actually thought it would be her and a load of homeless, drunken people. She had her eyes opened wide.
