What exercises HELPed you

What exercises HELPed you So basically I'm writing this to know what exercises you guys have tried to reduce or control your stuttering and it actually worked? So I have two weeks off and I really want to make progress with my stuttering thing. I've been stuttering for almost 20 years now and it really sucks cuz for the first i can actually mean it that ( You guys actually know how hard is to keep talking in your head, and spreading your information and everything you got inside of your head cuz you are not able to share them with others), its my last year in college and i will need to make few presentations so I want these presentations to be my way out.
