Now I'm imagining ordering coffee in an exaggerated pet voice. *Yes I would like a coffee! Yes I would!* I'm certainly not perfect now, but I'm a lot better than I used to be. What's helped me is utilizing this two fold approach. For the physical aspect, therapy can help if you find a good therapist. The point is to reteach yourself the sounds you have trouble with, which is really unnatural at first. But more than that, the thing that has helped me the most is getting a handle on my nervousness. It used to be before a presentation or something my heart would be about to pound out of my chest, which obviously meant I did worse. As I've gotten older, I've stopped caring as much if people hear me stutter. I don't use replacement words as often, I say exactly what I want to say regardless of my stutter. If I do stutter, so be it, I acknowledge it and move on. I'm not complacent, though. I still work at applying my therapy, I read out loud, I push myself to get better. You can't focus solely on the physical or mental aspects, you have to tackle both (in my experience).
