I've been dealing with tics since my childhood. I am 24 years old. I've tried tons of methods. I've found 2 good ways by myself to reduce tics. I have Neck moving right and left, breath out many times loudly and tighten my legs etc.
So I've tried to push tics away, not responding any pressure any tics but made worse and then I've tried to direct my tics. Let me explain with my poor english.
First tip;
My goal is reducing "visibility". Because i'm tired stopping tics completely. When I feel the pressure to "breath out or neck moving"(more visible tics) i tighten my legs(less visible side). It's like guied the tics over my legs. I feel like the energy want to comes out so i let the legs do the job until feel relaxed. When I tighten my legs 2 or 3 second the pressure was gone and in public that would be less visible.
Second tip;
I've directed myself to do all tics "only" at home. I've worked on this about months. I've hold my tics in public or school. If I can't hold the tics anymore. I go to toilet or some place that I can be alone I release my tics and when i feel relaxed i move on. So when I get home I don't do over thinking about tics , I do tics so hard I've never stop any pressure, I do all tics and realesed myself.
I am 24 , it took almost 18 years I've reduced %60 percent of my tics. Last of all being overweight and drinking too much coffee increase my tics so i walk 20 minutes everyday and drink coffee once a week.
