Is your odor coming from what you eat or is it coming from your backend? If it's coming from your pours i'd look to get tested for tmau if it's coming from the back end you should get in touch with a colorectal surgeon and try and get a defecography sorted out. What symptoms do you get? IBS? Incomplete bowel movements? Wetness and pain at the back end etc?
Btw sorry to get personal but the name leslie is it irish or scottish?
