Stims?

I’m just learning about stims, I’m early 40s and just been diagnosed and Have ‘unlearned’(!) my natural stims but I’ve realised my adult stims have been smoking, pulling my hair out one strand at a time if I like the texture of it, biting my nails and ripping the skin around and I love chewing constantly on gum, shaking my leg, I also play with my necklace a lot, I’ve just got a tangle teaser which I have on my I’d lanyard for work and I’ve started using gum again (I’m not supposed to at work but I can’t cope without it!) any other ideas that are discrete/ socially acceptable in a professional capacity? Since using tangle and gum I’ve been less inclined to pull hair, nails etc
