I never had such a thing when doing prep, but it is noticeable problem for me that when I have sweats that I develop an acrid body odour. Of course living on my own I don't smell it sometimes, until I go out and come back again - at which point I feel sorry for the people I've been dealing with. It's a sour, vinegary smell; I assume it is an overdose of the chemical that the biochemists have reported as isolating from sweat, that is the basic ingredient of sweaty socks odour.
I'm drinking lemon in water, in the hopes that whatever component of sweat is causing it would normally be broken down by the liver, and the help that lemon (and water) gives to the liver's functioning will help eradicate it.
On a bad day I have been known to throw out clothes because the smell won't go, but I've never been as unlucky as you Writer ! Have you given any thought to your skin bacteria colonies ? Have you perhaps been soaping excessively, leading to a bacterial monoculture that may express sulfides ?
When it comes to drug interactions, this is a very...interesting,
and under-researched problem. There have been instances of patients in ER actually not only smelling of chemicals, but actively emitting an unidentified gas, through the skin or wounds, that was so toxic that it forced the closure and evacuation of the clinic. This happened in a matter of minutes ! A full HAZMAT decontamination was required. As the patients died in each case (as I think may have some of the ER staff) it was never possible to work out what was happening chemically, or even what other licit or illicit substances may have been ingested. Plain fact of the matter is, there is no telling what the chemical factory that is our body will do under certain conditions, and with medications we may stray into unknown territory. Cheery thought.
