Thank you very much for sharing your story, it´s sad and beatifull because you defeated the problem. I´ve been suffering from smell of shit for almost 20 years and never tried a free gluten diet, i will give it a shot, even i don´t have much fate because i also suffer from rectal mucosal prolapse, wet anus and some more. I´ve had the same experience than you with my friends, most of them didn´t told me i smell bad except for one. The one that told you the truth... that´s a real friend man, take care of him because most likely he will take care of you with honesty and strenght. Best wishes.
