As the resident pit-stain guy in the office, I was desperate to find a solution to my excessive underarm perspiration. Whether it was being asked to get something from the top shelf -- or the never-ending requests to do the "field goal" signal -- my coworkers shared many a laugh at chatchi's expense.
While it is not uncommon to have perspiration rings under the arms of your shirt, it IS uncommon to have those rings bleed down to your belt. Doctor's call it Axillary Hyperhidrosis -- chatchi calls it "Swamp Pits". My perspiration was becoming so unmanageable, I would wear four (4) undershirts to prevent the stains from bleeding through to my dress shirts. The idea worked, but the extra layers only caused chatchi to sweat even more.
The average adult perspires a little more than one quart of fluid per day. chatchi perspired more than SEVEN quarts of fluid per day. After failing numerous job interviews, and scaring away an immeasurable amount of potential romantic companions because of my mind-boggling sweat production, it was time for me to get help.
My search ended with Certain Dri. This remarkable, non-prescription product is applied to the underarm area before you go to bed. While the concept might seem unusual, you wouldn't be reading this review unless you were used to going to unusual lengths to prevent underarm perspiration.
Certain Dri is applied in place of your regular anti-perspirant/deodorant, but I'd advise still using a scented deodorant every day, since Certain Dri does a less than adequate job of masking the stench.

It’s nice when a product works EXACTLY as advertised, which Certain Dri PM Roll-On does. This is one of the few products I have used that TRULY works through a strong antiperspirant action. That is, it does NOT use scents to cover up odor from sweating, but rather dramatically reduces sweating, and hence dramatically reduces odors. When at least 15 other deodorant/antiperspirant products didn’t, THIS is the product that allows me to wear light blue shirts.

Everyone produces sweat under his or her arms, and this type of sweat has an odor to it. However, not everyone sweats the same. Some sweat more than others, and some sweat has a more noticeable odor. Stress can accelerate not just the quantity of sweat, but also make a more concentrated odor. I have a tendency to sweat a lot when wearing a sport coat. It's not something pleasant to talk about, but I historically would have to specifically only buy certain color shirts, and refrain from taking my outer coat off because I felt it was noticeable. This bothered me greatly, often accelerating stress, and ultimately making me sweat more. Yikes :(

I've tried many different deodorant/antiperspirant products, including some of the "clinical strength" products sold over the counter. Some worked better than others, but none had dramatic results. A friend who suffered from the same issue recommended this Certain Dri, and specifically this Certain Dri PM Roll-On (found in a green and white box.)

Well, this product has been reviewed to death, so I'll just add to what everyone else has said. First of all, the results aren't instant for everyone. It took about a week and a half of use every night for me to see the amazing results that everyone talks about. Now, after about three weeks of use, I am entirely sweat-free. I am planning on gradually reducing my use to see how infrequently I can get away with using it before the sweating becomes a problem again.

Second, not everyone feels intense burning or itching when they use it. I didn't feel anything when I applied it, and I actually wondered if I had done it wrong. So the second night I put on about 5-6 strokes instead of 1-2, and I felt a little tingling, but nothing more.

Sweating was a moderate problem for me, enough to be annoying and slightly embarrassing. It definitely affected the type of clothing that I bought. Now I have to train myself to look at whatever clothes I want, instead of thinking, "Too bad I can't wear that, I'd have 3-inch pit stains by 4th period." I think for people like me, this is a great solution. If excessive sweating has affected your life in even a small way, it's worth giving this stuff a shot. For me and many others, it really is a miracle product!

Edit March 2008: Still on my first bottle! I only use it about once every other week now, and I still don't sweat AT ALL, even during my track workouts. I did experience some pretty intense burning/itching one night when I applied it to freshly-shaven skin. DON'T DO THAT.

Edit December 2010: I haven't used Certain Dri in about two years, and I still do not sweat. I think my sweat glands have been permanently altered. I don't know how this stuff works, but it was without a doubt the best $6 I've ever spent in my life.
