I had same symptoms and read 5 months day and night until I found the answer- we are all infested with parasites, but the one that makes bloating and chronic fatigue is the rope worm- search for Gubarev protocol and do that at home - You will be surprised!!!

Wish You luck! http://en.shram.kiev.ua/top/patents_medicine/medicine_13/medicine_4.shtml
