That is VERY interesting. My ex-husband used to get what I called the "funny" smell. I had no idea what it was...but it wasn't a "bad breath" thing. And I know recently his blood sugar was testing high. That was when I was a smoker too. I also smell chlorine in water. I'm wondering if I shouldn't get the blue foam like I had planned too this week ::gulp::
There was one other medic there who could smell it. Also a woman. Maybe its a gender thing. As for animal urine, yep. (We have very clean litter boxes in our house, LOL) I can also tell when the cats are getting sick because they smell funny. Guess theres an upside too! Being able to smell ketones could be a good thing for you. I'm curious, does your husband vape. If he does, I was wondering if it seemed to have any affect on his blood sugar? I know smoking does, but I wasn't sure about vaping.
