I am a very sweaty person. It's all over but especially bad on my palms, feet, thighs, and armpits. I have a prescription antiperspirant but it just doesn't cut it. I've heard there are surgical options for excessive sweatiness, but what else can I do?

It's not how healthy you are, rather using the right products to combat the bacteria on the skin and keeping perspiration in check. Here is your solution and I know it works! Drinch a washcloth in rubbing alcohol. Wash really good three times a day for a month. You will notice benefits in a day or so but keep doing it. Throw away all razors and deodorants and buy new. Use a prescription strength deodorant (they sell them over the counter.) A good one is Suave clinical protection. It will keep you fresh and dry. For feet, soak them in alcohol (u can reuse once or twice too!) daily for twenty minutes for about a month and then only once a month. Throw away all old socks and shoes and get new ones. Put baby powder in your socks and in your shoes daily. Your feet will stay fresh and dry.

How old and how healthy are you? That is where I would start. Excessive sweating can be a symptom of several diseases. If you approach it strictly from a cosmetic point of view and only talk to doctors that approach it from that point of view, they are going to give you what you want and may miss something important.
