I was diagnosed with tourette syndrome in 2012. Ever since I find it really hard to stop the tics that I have. Is there anything I can do.

Go to Neurologist. There are a number of available treatment options for "Tics" that have been studied in controlled trials including Dopamine D2 receptor antagonist therapy, Dopamine agonist, Habit reversal therapy. There are many other drugs that have not been studied but may be helpful Guanfacine, Clonidine, Norepinephrine reuptake inhibitors, Botox, Baclofen, Tetrabenzine, Benzos. SSRIs ect. Go to Neuro or Psych.
Many meds. Sometimes it is difficult to find a successful medication which can stop the movements, and a series of med trials must be endured. However, if you can tolerate Orap, (pimozide) might be one acceptable choice. Find a movement disorder specialist and pursue this.
Medications. See a neurologist to discuss medications commonly used to treat tics, such as clonidine, giants one, climax roam.
See the Dr who Dx'd. Adult onset TS is less understood than childhood onset but there are some treatments found to help. It's not dangerous and the meds can be, so bahavior therapy is a 1st thing. Neuroleptics and blood pressure meds can work. Here's info: http://www.ninds.nih.gov/disorders/tourette/detail_tourette.htm#262233231 and http://adulttourettes.tumblr.com/ Best wishes for success!
