Try some cornstarch--it's more absorbent and less pore-clogging than talc. For a little extra anti-stench boost you can toss in a little bit of baking soda (try a mix of 3/4 cup cornstarch and 1/4 cup baking soda and apply with a powder puff).

i don't think i could give up my antiperspirant... but that is eye opening

C - There are deodorants that don't use aluminum. I use Tom's Lavender (they have them at Target!): http://www.tomsofmaine.com/toms/product.asp?dept_id=500&pf_id=BW-ND

There's also JASON brand, which I haven't tried, but I've seen them at Target also:

They don't work as well at odor-protection as aluminum-containing brands, but they work a lot better than nothing at all!!!

have you tried any of the mineral salt deos? they'll do nothing for perspiration but the better ones will kill odors dead.

i tried them when i gave up the anti-perspirants for the same reason. i think it was two weeks before i fell off the wagon. i need that silky smooth feeling in my armpits that only a disease-causing agent can provide.
