Should you stop cracking your knuckles?

Given that knuckle cracking is mostly benign, there might be little impetus to stop. If you do want to, though, Jagannathan recommends conditioning yourself with techniques such as cognitive therapy, to understand what you're doing and to find distractions that prevent you from doing it. For example, you could consider keeping a log of your triggers (do you crack your knuckles when you're stressed, bored, or do it without thinking?) and try busying your hands with stress balls or fidget toys.
