No problems, ask me whatever you want. I am truely no expert, but i have learned so muh through my battle. There are actually quite a few people who got the odour after using Acne treatment/ Antibiotics . I think they just run down the whole immune system and kill all the good bacteria in your gut, letting Candida/ parasites and whatever else take control.
I noticed you said your sons room smell really bad in the mornings etc, this was totally the same for me. Everywhere i went i left an odour for ages. My room smells normal now, i have done trials with my mini step brother...little kids don't lie.
