Tips from People that have lessened or gotten over stuttering?

Tips from People that have lessened or gotten over stuttering? I've met a couple of people who tell me they used to stutter, but it just eventually went away. I think those are people that just talked to fast and now they don't. Seems impossible to get over a real stutter. Has anyone on this sub made a real leap in fluency by trying some things? Or has anyone just simply gotten over it? Any tips or tricks from you are much appreciated. ​ On a side note, has anyone else noticed their speech gets really really bad when they are sick or getting sick? ​ Help us out please!!!
