Apparently, we are not all created the same. I did the vegan route for 20 months and had to give it up as even my vegan naturopath told me I'd have to at least eat fish to survive. A lot of bad things happened. My hormones shut down, or close to it. My hair was falling out. My high blood pressure got worse instead of better. I lost too much weight. I began to experience various fungus problems, so much that one doctor ran tests for Aids, even though I thought there was no possible way except for blood transfusions many years before. My cholesterol dropped, but the balance was all bad, and that's just a few things that went wrong. Listen to your body. I should have done that a lot sooner than I did.
