Hi! I have been researching the heck out of everything for a few months but am no expert. I have read however, that people with TMAU first get much worse before getting better AND that their smell can be many different things like garbage, fish, rotting meat, chemicals, etc. I've also read that when there is more choline, it tends to smell like the other smells, and when the choline decreases in the body, it begins to smell more like fish and less like garbage, meat, etc. Glad to hear you are improving and good luck with the test!
