This is probably contradictory, but does anyone use an alum block (crystal stone/spray/etc.) AND an antiperspirant? I know antiperspirants are not loved around here, and I really don't like using them either, but I need to control the sweat. So, the alum would help clean and kill bacteria for the odor and the antiperspirant would help regulate sweating. Is this a dumb idea? Anyone use both?
