Since I've stopped eating bread I only have sinkers. No more floaters, no more stinking toilet, no more multiple flushes. I still don't know exactly what caused it, if it was the gluten or the modern issue that industrial bread (even whole grain) isn't given enough time to rest (long-term fermentation?) so that it then continues to work inside the gut causing the problems, given a certain unhealthy gut microbiome which either can't deal with it or somehow goes crazy on it. It was not just bread, though. Also oatmeal and cereals, so it isn't that clear. It was always related to the amount of gas which would end up in the feces.
