EDIT: Dragonflight update -- This loads SUPER slow, but works pretty great once it caches everything. I'm not a developer, so if anyone knows a fix for this, let me know.
This was inspired by some of the other somewhat outdated addons that did current expansion water. I went a little further and included food and water for every food and drink item I could find on wowhead.
This may get a little goofy when you have buff food that does both mana and health, but hey, it is what it is. Let me know if there's anything drastic that happens that doesn't seem right.
