I sweat A LOT. I'm of Eastern European descent (pale white skin, grew up in cool, dry climate) so hot, humid summers in NY don't make it easier. I have little problem with sweating though. I follow some elaborate procedures to stay dry, fresh and clean at work and that works. Other than that, I don't care. I 'd change clothes and shower a few times a day if it gets really bad. As long as I don't stink offensively I can sweat a river so I follow my anti-stink procedures and I keep sweating

Try avoiding caffeine, alcohol, carbonated drinks (soda) and spicy food on hot days, they'd make some people sweat and/or stink more.
