I'm going to try and be as logical as possible here.

1. Good for you. I know that some of us vegans can be a pain in the ass and it really does give vegans a bad name... but
2. I think if all vegans were just loving and accepting, the people who want to continue eating meat would find a new excuse not to go vegan... which leads me to
3. The nutrients you want to get from animal products, the animals got through plants. You're just adding a middle man, plus cholesterol.
   The amino acids you get from animal protein, they got from the plants. Our bodies can not use protein, they can only use amino acids. When we ingest amino acids in the form of protein we add an unecessary step to digestion, of breaking down the protein in to amino acids, that is extremely taxing on our digestive system, specifically our colons.

Humans evolved to eat animals to survive in cold climates and when food was scarce, however that is not the case in most of the world any longer. It's modern obligation to do the least harm possible, and that should include to yourself.

I'm not trying to discourage you, but I truly think if you give this a REAL shot, don't PLAN on stopping... you will truly reap the benefits.

It's an amazing journey. My dad said he'd never go vegan, and then he did... and now he's healthy again :)
Then my step mom went vegan, and her sister, and my step sister...

No one ever regrets it.

Also, if you start feeling like crap in the first few days, you're detoxing from all the garbage you've been feeding yourself. IT'S A GOOD THING!!
