OK, I'm a sweaty kind of girl. I know it sounds pretty nasty, but it's the truth. When the snug fitting t-shirts came into fashion, I could wear one for an hour or so, then the pit stains began! My ordinary deodorants would eliminate most of the offending odor, but NONE of the perspiration. I have tried every deodorant out there, and although some worked better than others, not one did a bang up job as a whole. I saw a commercial for the Secret Clinical Strength and thought, what the hey, I'll give it a whirl. When I actually got to the store to purchase it, I was a little taken aback by the high price, but who can put a price tag on beauty? After I got home and read through the instructions (i know, instructions on deodorant), I realized that in order for this deodorant to work, you have to put it on before you go to bed at night. Since I shower at night, that's not a problem for me. I tried it the first night and the next day got dressed as usual although without my usual smear of deodorant. Guess what? IT REALLY WORKS. I was astounded to not have to be embarresed by those awful stains that look so tacky on a girl. You do need to put it on at night if you want it to work properly, though. I have tried it in the morning, just not the same. Apparently the ingredients in the deodorant somehow determine how hot natured you are by adjusting to your night time temp. I don't exactly know how it works, all I know is that it does work. Now I can wear my little T's and not have to cover up after an hour to hide my fatal flaw.
