I believe most doctors know if their patients are alcoholics--they just don't want to be involved---the doctor is covering his ass by ordering a CT Scan-because he has a patient c/o dizziness.
Maybe it will show alcoholic dementia--now that might be an eye opener for him.
He must have blood work done every few months if he is on Lipitor? His liver enzymes--do they come back normal? I doubt it.
