I know how hard this is. I've recently contracted something to make me smell too and it is's horrible. I'm also on the candida diet. which is really hard, I think (hope) it's candida and i HOPE this diet will CURE ME.
the difference between candida and tmau from what I have gathered is that tmau is very very pungent.
but you should get checked for it JUST in case.
Leaky gut also. It can happen as a result of candida (yeast) perforating the walls of your intestine causing toxins to leak into your bloodstream (hence the smell)
If you're gassy, bloated, have diarrhea/constipation you could have I.B.S
