Has any of you managed to go from a severe to a mild stutter as an adult? How?

Has any of you managed to go from a severe to a mild stutter as an adult? How? I need some practical advice. I'm almost 26F I can't live like that anymore. I have to learn a way to lessen it. Should I read aloud everyday? Should I do diaphragmatic breathing exercises everyday? How can I learn to control it so that it's not as prominent and limiting?
