Happens to anyone really. You cut out bad food your body has been tolerating and it stops tolerating. (I’m not vegan, but milk based stuff, fatty foods, fast food, and a bunch of other shitty for me stuff stopped being acceptable to my body once I stopped eating them regularly. Unfortunately I also suddenly go5 super reactive to eggs, and I love eggs. No more delicious yolk for me T_T)

Second note: ( I don’t actually have any issues with vegans. I think ultimately they are probably correct, but I still eat meat anyway, just as I also post this response on a Samsung cell phone that probably had slave labor involved in some part of its production).
