Man oh man, can I identify with the "medication quest"!
I'm in pharmacy school, and it was SO difficult to keep my fingers out of AH's business when it came to drug therapy. I'd switch right into counseling mode, and, without fail, he'd do exactly the opposite of my best clinical judgment.
Good for you for taking care of yourself and letting him attend to his own affairs!
It's not an easy thing to do.
