I also have this problem. I have been using Certain Dri at night for several weeks now and it works great. It is OTC and I found it at Walmart. I actually had tried a prescription strength anti-perspirant and it was too strong. This one seems milder but it still works. You apply it at night and it shrinks your pores or glands. You cannot shave and then use it though. I usually shave each morning and then use it at night and it hasn't irritated my underarms. This product has helped me tremendously!! I love it!!! This is the first time I have been able to wear a tank top. I feel more confident than I ever have. Kim
