Good luck. Depending on your body and your stores you'll feel good while your cleansing for maybe a few years then BAM, you realize veganism is not the ideal diet when the health problems start.
Vegans never listen to ex-vegans. We need animal food to nourish ourselves. I would share a video with you, but it'll probably be downvoted by you people.
The way we produce our food is bad whether it's animals from a factory farm or plant food.
