Answer:
Don't focus on it. If you know you have a tic, try forget about it, try to get sleep so that when you do have tics they will be weak
Explanation:
A tic is a random or sudden, involuntary, repetitive motor movement or vocalization involving distinct muscle groups. Motor tics can include eye blinking, nose crunching, pulling at clothes or touching others. Vocal tics can include clearing one's throat, expressing simple sounds or uttering curse words or racist terms
