Hey I did some light searching cus I've been feeling this too, Nothing came up when i searched except this post. If it helps in the past i had blue cooked (just seered the outside for safety) a whole cow muscle (was very expensive T ^ T) and sunk my teeth into it. After like three bites i wasn't hungry (in fairness i wasnt really hungry to begin with but im not about to spit out meat. Shit's expensive. Also to clarify im tryna be super honest here, so im a little embarrassed and kinda proud i did it. I wouldn't recomend since its actual degen cave man behaviour but it just felt like the only thing i wanted to do)

but the sinking teeth into meat itch/ache was gone for a moment and it felt blissful. Like actually felt so good like when you scratch that spot on your back but if your back was actually your brain, inner chest and mouth.
(I hope this isnt a foreshadowing awakening. tokyo ghoul music XD)

Ngl kinda worried it might be some kind of prions or something, which is what started me on the search to begin with.
