I have ADHD too. Have you looked into fidget toys? They dramatically cut down on my toe-tapping and fidgeting. Also the incidence of distracting fidgeting goes down when I'm at a good level of meds+therapy. I might also add that (this obviously depends on local laws but) you can see if there's any disability protections you can take advantage of. Where your company can work with you to help you work better, or at worst, at least, not fire you just over a disability.
