I felt bad about making fun of your plight, so I decided to see if I could find something that might be useful.
Here is a site selling the same kind o mineral compound I used for a while. I'm not suggesting you buy from them, but it gives you an idea what it is and you can shop around for the best buy.
The key is that while you will sweat, you will not have any odour. Now maybe you have some kind of condition that it can't beat. All I know is that it worked for me and a gf I had at the time. The only reason why I stopped using it is that I decided to stop using anything altogether, except every once in a while using a simple anti-perspirant when that's what I'd want to stop.
I don't know if you shave your pits or not, but shaving does reduce the smell (reducing areas for bacteria to grow). Personally I like girls with armpit hair so I'd hate to recommend that, but there ya go.
I can't imagine having my own body smell cause me physical pain. The more I think about it the more I feel bad I made my joke. Sorry.
