I agree with Jacqueline in seeing a doctor as it could be thyroid or other related issues. Caffeine, garlic, and spicey foods cause the body to sweat more. Drinking green tea can help.
Deoderant alone doesn't stop sweating, antiperspirant does. Check the deoderant your using and make sure it has antiperspirant in it.
You really need to see a doctor. You could have that sweat problem that needs special attention - special deodorant ...
ive heard if you put hand sanitizer on your underarms, it keeps you from sweating, crazy huh?
U must c doctor just to assure wat it is
