If thoughts of self-control are constantly flying out of your head during the game, you can make a big note to yourself. For example, draw something large and bright on a piece of paper, it can be the word “Stop” or some symbol that will immediately remind you of control. And while you are playing, this note should always be in your focus. Accordingly, if your brain learns to react to the note in time, then there will not be any serious problems with the game and you will not have to over-emote. That's the idea.
