These are precious stories, I'm lovin' it!! The best trick I have for masking those unpleasant odors is a little Vicks Vaporub under my nose. Works like a charm!
Pre-pouring meds is pretty common where I work too. It's allowed as long as you keep them locked up and don't pour too far ahead. Sometimes it's just a necessity because of everything else going on. But those med times are atrocious!!!!
