Deodorant and anti-perspirant are different items. Deodorant keeps you from smelling, while anti-perspirant keeps you from sweating so much.

There's lots of things that can cause a lot of sweating such as stress, physical activity, or simply being a little overweight. If you don't have the problem at home then, it's probably stress and excitement.

you have panicky gland activity--I suggest an operation

Some people sweat more. You should use some baby powder for your pits.
