The damned letter “c”

The damned letter “c” Hi all, pretty new to Reddit so if I’m doing something wrong don’t come at me too hard lol. Anyway, I stuttered really badly when I was a kid up until about middle school where I met an awesome speech path (about 20yrs ago) and almost everything is gone except for a few scenarios and the damn letter “c”. It’s fine for me if I don’t start a sentence with a “c” but my new job all but requires the word “control” to be used every time I use a radio which is all the time. Any tips or tricks to getting over a certain letter besides the basic repetition and slowing down? Thanks! Edit: Thank you all so much! I have so much more confidence now trying out the different methods! Thanks again!
