What can I use ?

Hey y’all! What can I use to stop my armpits from sweating so much ? I need help to reduce the sweat. I talk to my doctor he said it’s nothing he can do but I feel like there is a way to help reduce sweat. Yes! I shave but I sweat like crazy for no reason and it leave a stain on my shirt. I don’t know if it’s the deodorant. I don’t smell which is weird but it make my shirt look a mess. Help me please. Tips anyone ?
