Delivered via House Elf to Zacharias Smith while he's in the hospital wing. Zach, I very much never meant for you to eat ALL of them, especially not in one go. You've no reason to trust me right now, so I don't blame you for not buying into this, but these will help. Don't drink coffee; that'll just make it worse.
Feel better. I really am sorry for all this; I only meant to get you to chill out a little bit.
