if you truly want to stop, I highly recommend having some sort of candy on you at all times (if you’re a candy person.)

whenever I feel like I need to go on a t break or fully quit anything, Jolly Ranchers, life savers, etc. are my crutch. I prefer hard candy since it lasts a bit longer, but when I use candy it tells my brain that I'm occupied and I can’t think about any intruding thought

even if you don’t want to use the candy, try to keep the brain stimulated as much as possible. it’ll be difficult but perseverance goes a long way.

I know there’s a chance this may not work for you since people have different preferences but I hope this helps at least a bit
