Like 7 years. Sometimes it smelled like sewage, sometimes like shit, sometimes like some kind of chemicals. Rice was the biggest culprit. Then 2 years ago I started to smell like a dirty sock when I ate peanuts. Other nuts ok, but not peanuts. Protein and vegetables only now. Start with a vege diet for a few days and if no odor add fruit. Than add meat. Also must do cardio to improve metabolism, as this helped me. I must have certain bacteria or a unique combo of them which cant be killed w/ Antibiotics .
