wrt not using deodorant, personally I use unperfumed aluminum-free deodorant. TBH, it's not as good as regular deodorant; I wash my armpits and apply fresh deodorant daily, whereas with regular deodorant I can go for ~2 days before my armpits starts to smell (when not doing anything particularly physical).
