There are tons of vegans out there that don't get sick etc..If you get sick on vegan diet..then it has to do with your body, thoughts etc. If it were true that vegan diet makes you sick..then all other vegans out there would be sick. Eating vegan diet and having thoughts about meat, meat, meat..will make you sick, you may not be aware of it. Our thoughts, belief system play such an important part of our life and what happens to us and how we feel. Bottom line, you love food, you love meat..if that is your desire and then going on a vegan diet..you will crash, as you did. It is very sad..but now your desire for meat is fulfilled..I give you some time, then you will have other complains of sickness and ill health..what then? you will blame the meat eating..it all goes back to your thoughts, and beliefs..that is what make you who you are today. Honestly, I cannot put a piece of meat in my mouth without feeling guilty..it just doesn't feel right. You know I used to eat meat, about 7 years ago, I have been vegan, before when I ate the meat..I suffered anemia, taking 3 pills a day. 7 years later, i have been cured..no more anemia, no more pills, protein, b12 etc..all normal..
To each his/her own. Good luck on your meat diet.
