Deodorant does not stop sweating; it kills the bacteria that causes the body to smell.

Antiperspirants clogs the sweat glands and prevents sweating. If there is no sweating then there's less bacteria to smell therefore acting as a deodorant.

If you're buying deodorants, it's not going to stop sweating. You should buy antiperspirants. Some of the strongest antiperspirants you can buy are Arid XXX.

You can also go to the pharmacy, and ask them if they have any clinical strength antiperspirants.

Good luck.
