Your not crazy

If you want answers from a legit source you should go to this website
http://www.monell.org/contact_us/tmau

It is a center where they study TMAU and other strange odors, you can contact them and ask them all the questions that are on your mind. I actually asked them a couple questions myself and they responded.

Also, there are ways of treating TMAU all you have to do is have a low choline diet, and take chlorophyll and maybe activated charcoal to cleanse the toxins(odors) from your body.
