I don't normally perspire heavily, and have never needed to worry about it before. However, due to a job move, and a consequent longer walk to work, my underarms are letting me down(!). I wonder if someone could recommend a really reliable antiperspirant so that I don't have that awful fear of raising my arms (in case there's a wet patch). What's the best one for women (anti-p, not deodorant necessarily)? Thank you.
