Edited to be simpler and to further clarify:
I have been living as a temporary Vegan, though I have always been someone who mainly eats as 'organic' as possible. Mostly it's been something I've always wanted to try, just to see how it was. For about a year, I haven't consumed meat or animal by-products. Partly for the sake of the guilt I feel about the treatment of animals, that I can't deny. Though there are meats and animal by-products, that have come from animals who are well-treated, and are killed humanely. Their meat also treated well and delicately from animal to store shelves. These meats and by-products are far more easily accessible, but are considered a bit more expensive. Also, I wanted to try it because it forced me to find different foods that I now absolutely adore. I may not have searched them out, if I hadn't been forced to. Hummus being a prime example.
Some of the 'benefits' of Veganism for me have been: I felt better overall for most of the day, and I appear to be less tired during my usual schedule. However, I found this to be temporary. Probably because I increased my vegetable and water intake by 100%, while before I was hardly eating any of it before. I probably felt better because I was getting more of what I needed, not because I stopped eating meat and animal by-products. However, I am becoming increasingly tired, even though I am following Vegan diets to a 'T' to make sure I get everything I need, I've also been getting far more depressed. My BODY doesn't seem balanced. Most Vegan and Vegetarians diets are carbohydrate dependent, or their carbohydrate intake increases considerably. Which mostly breaks down right into sugar that the body doesn't need, and should probably be eaten less then anything else.
This isn't something I planned on doing long-term, 'until the end of my days' thing. But I've enjoyed the self-experiment,the different way of living, an extended palette, and plenty of new things to enjoy and add into a new diet.
