Interestingly (and awesomely) enough, this is the second blog i found of someone trying veganism and liking it a whole lot, enough to actually change their way of life.
This guy at a blog called raptitude did a vegan experiment here is the final write up http://www.raptitude.com/2011/03/what-i-discovered-when-i-went-vegan-for-30-days/
He decided afterwards to become fully vegan. I was very surprised cause he came into it more as an experiment, and not focusing on ethics. But it made him feel good and the ethics sort of fell into place it seems.
Heres what he said about it
Try a vegan diet for 30 days – DONE – 3/24/11 – This became Experiment No. 10 and it has left me changed forever. I am now vegan and have no plans to change.
