I prowled the antipersperant aisle at the grocery store this weekend and came home with something a little stronger. I was using Dove, which has 18.5% of whatever the active ingredient is. I picked up something that has 19%. Not a big difference, but the 20% was the "clinical" strength, and that stuff was $8 a stick! I'll try the 19% first.
We had a cold snap this weekend, and this being Texas, my office is heated to a tropical 78 degrees. I'm dewy, but no one has passed out after walking into my office yet, so I think the new stuff is helping.
