I'm glad to know there's other people in the same boat. I am very sweaty (even when it's not hot) and it's the bane of my life. It's very embarrassing - not just the wet patches but the smelliness depending on what fabric I'm wearing. At the moment I'm using Dove spray-on because roll-ons just don't seem to work for me whatsoever. But these tips have been good - I'll try some others.
