Damn right
My pharmacist likes arguing with me about medicine I've been taking since I was 5. Every time I go to get it, I get the third degree about do I know how to use it, has my doctor given me clear instructions on it, do I know that it has these side effects...?

Thankfully, due to a curious childhood, I'm able to list every fact about my medication in Chemist!Spiel and explain very patiently exactly what I know... while said chemist checks the information sheet and looks embarrassed. It works quite well, but I guess not if you're in agony.

Also, if your nurse doesn't know what a catalyst is... run away.
