More Info
Thank you people for your responses. So many questions! A family support person made the drinking suggestion. I do not know whether Listerine can completely cover the alcohol. Who can give ma an answer on this?
If you can definitely smell the alcohol on a person even though they use Listerine then she can not be drinking while around me but may still be drinking when away in the City.
Her father was an high-achieving professional abusive alcoholic who made his kids' lives hell by verbal abuse night after night once he was drunk.
They were never good enough for him. My wife's behavioiur has changed dramatically since her father's death. Also her sick old mother was abusing alcohol until whe was put in a frail care home. The family is generally in denial about their parents drinking.
Does this bit of info help?
