You have two changes at once here. You cannot attribute anything until one of them moves.

Bring a list. Embarrassment makes everyone forget things, including you.

Enteric coatings should not be crushed. The pellets are the delivery mechanism. How long have you been on a shortage?

Ten percent cuts, of the current dose not the original. That is the arithmetic that keeps it survivable.

How do you tell the difference between the drug working and just a good week? Same for me with a shortage, unfortunately.

I would stop trying to convey how bad it is and start saying what you want them to do.
