No and no.

But don’t confuse awakening with enlightenment. It is somewhat beneficial to not drink alcohol and eat meat before awakening, I agree with Ramana here. Especially alcohol. It’s somewhat beneficial, but not required. Do what you like.

After awakening, there cannot be any restrictions, I agree with him again. Awakening/self-realization is the realization of your own freedom, if you are looking to others to tell you whether you can drink alcohol or eat meat after that, how can it be freedom? Everything is allowed, there is no problem. No rules can apply.

It is my experience that in enlightenment it becomes impossible, not because of the rules, but because the body rejects it, it’s not what the body needs. When the body is free from all conditioning of the mind, it doesn’t want neither alcohol nor meat. Both meat and dairy don’t taste very well to humans, we only get conditioned to eat it from the early age, so we don’t notice. Believe it or not, it actually tastes pretty nasty hehe. Same goes for stuff with lots of sugar in it.

Beyond enlightenment it’s fine again. :)
