ditto on my scent changing when ill/stressed/etc. there's also a terrible 'travel funk' that happens (not just to me!) when i've been in a car/plane/whatever for a long time.
for a while i made a mix of baking soda & cornstarch, patted that on with a cloth, & dabbed a bit of lavender or peppermint 'around' (since peppermint is too strong for direct use there, for me). i've also gone a long time just using some of my homemade salves that only have herb-infused oil & beeswax, though that's not amazingly effective, only mildly so.
i don't mind using essential oils, but since i don't make them myself, my mind is always stretching for something i can produce on my own. maybe a peppermint or lavender or lemon balm triple-tincture, where multiple batches of the herb get infused back into the same alcohol.
i'd also just like to get back to a living situation where my natural smell is fine again. i don't like worrying about being treated poorly Or upsetting people because i smell like a human animal.
