Trying to redirect or eliminate specific ticking behaviour

So far there are certain activities which make me want to tic so bad that its nigh impossible and on at least one occasion I've had to allow myself one tic. The goal is not to tic with my hand anymore as it is causing tendonitis. Ive been able to greatly reduce and almost eliminate this behaviour so far although sometimes , I'll have a gentle tic where instead of clenching, I smoothly rub the inside of my palm with my middle , ring, and pinky finger . I try and avoid this, too. It does seem like I still engage in various nervous behaviours but as long as it isn't giving me tendonitis, I'm satisfied. I tend to rub the tablet against the inside of my palm. While drawing, its more difficult not to tic. Also while playing a game. Anything that requires great focus makes me tic more.
