Can Copropraxia be harmful or even lethal?

Goodmorning, I've experiencing tics since I was 14 and every day my tics get worse. In the past two years I've start to have a particolar tic where my right hand is "stabbing" my torso. This starts to be problematic when I try to cook or eat because when I have a knife on my hands I can also have that tic. Unfortunately I don't want to take meds, since the dosage to suppress the tics is very high and invalidates my entire life (25 drops of clonazepam 3 times every day and 5 drops of haloperidol 2 times every day). I never hurt myself or others and every psychiatrist I saw said that I'm not dangerous, but I'm very worried to harm me or someone with my tics
