I've been a vegan for about two months now, and I love it.
I've never felt so good, energetic, and at peace before. Before going vegan I would end the day feeling terrible and guilty about my food choices throughout the day, now I go to bed feeling happy about myself and the way I'm living my life.
I've also lost some weight, which is cool cause I've always been self-conscious about my weight.
Here is what I've been able to achieve, picture on the left is from December 2012 and the one on the right is from 2 days ago.
