In addition to the great recommendations below, have you thought about changing your diet at all? Some people's bodies react weirdly with certain foods, especially things like onions and garlic. If my fiance eats garlic, about a day later he will have the worst body odor for another day or so until it is out of his system. It won't help with the sweat, but sometimes body odor is both the products of the bacteria that live on our skin, and the things working their way out of our bodies!
Crazy enough i use mens deodorant. it just works better, and im not a fan of scents. I use Mitchum. Ive used my hubbys unscented gel one and i think it works better than the womans version so i like to use that in the summer. But most of the year i will use the solid stick . Ive tried the womans powder version and dont find it to last as long so i use the mens instead
Dove Clinical Protection is also really good. Makes me not sweat during the summer. But it is also good to put on deodorant before you go to bed and again when you wake up.
Re: Smell[ Edited ]
I use this as well. I sweat so much its awful I'm really quite embarrassed about it, even though I shouldn't really be. I'm on medicine that actually causes me to sweat more and I despise it. This is the only deodorant that I wear now and it really, really works for me. I don't have sweat seeping through my shirts causing pit stains (ha) , or any icky sweat smells!
Ah, you are the person with the foot odor too. You should try to Secret Clinical Strength but you definitely need to be seen by a doctor if your whole body is sweaty and smelly. Good Luck!
