DP or whoever else you could possibly ask (since they'll think you are batshit!) and tell me what it smells like?!
I posted about my DH's breath months ago because I think it has a really distinct, noticeable odour (not bad as such, and not typical "bad breath", just a very specific smell) and nobody recognised it. In fact, google tells me I'm one of the only people in the world connecting a breath with this particular smell - when my OP googled it he found my thread!
So please... could you describe your DH's or another's? I'm actually a bit worried! He's been checked for diabetes and has no other known health problems. I'm breastfeeding so think my sense of smell is heightened but it's really noticeable to me when he's talking (but as I say it's not a "bad breath" smell)
