I read an article that said you should put deodorant on BEFORE you go to bed. That way it gives the active ingredient hours to sink in and keep you from perspiring and smelling the next day. If you read the box on those new prescription strength deodorants, it says the same thing, put it on before you sleep.

So I've started to and It works. I never have to worry about smelling. And I don't have to worry about applying it in the morning, but immediately sweating and ruining the usefulness of the product, because you don't really sweat much at night due to lack of activity. It's the perfect time to apply it.
