I have allergies and wanted a good, strong, hypoallergenic antiperspirant. Bad move. For one thing, I had to use so much of it that I had all of this nasty residue on my shirts that didn't come out in the wash. I had to put on gloves and rub the fabric vigorously in HOT water (ouch) before doing a regular wash load.
Another issue was that I sweated anyway, profusely! The products didn't even put a dent in the perspiration (and, of course, they did nothing for the rest of my body). The last issue was that I smelled anyway and even smelled worse with certain products.
I've reconciled myself to the sweating, but I use a Thai stick that controls the odor quite nicely, and I put powder around my crotch and related areas in warm weather. I think that this is the best I can do. Heh. I'm sensitive to the cold, so moving to the Gobi Desert definitely is not in the cards for me.
