I might sound like a crazy person, but I recently noticed if I go from an “m” sound to a “k” or “c” sound my lips make a very audible pop sound. The kind like when you put your lips together and blow out quickly.

Is this normal? Because it’s freaking me out and I can’t not notice it no matter how hard I try. It’s gotten to the point I’ve basically stopped talking unless absolutely necessary out of fear it might happen.
