Another vote for Secret Clinical Strength.
I perspire heavily, all the time. Even when I'm not working out. I can only wear dark colored tops to work because by the end of the day I have wet spots under my arms. Very embarrassing. But, that's all changed with Secret Clinical Strength. I sound like a commercial, but it's the first thing I've tried that actually works for me.
I try to put it on before bed, but I don't always remember. During the week, I put it on in the morning, too, after I shower, but on the weekends I don't.
