Hi, I am in the same situation. My son has had tics that come and go for years and recently they have been horrible. He even tics as he sleeps. This week they have been non stop. I was praying --deep prayer, father God take away this disorder ---when Jesus's face came to mind and the words sertraline. Research the sertraline ---which is Zoloft. As my son drifted off to sleep I grabbed my phone and typed in the phrase zoloft and tics. LO AND BEHOLD it is a factor. Case studies proved that zoloft causes tic disorders. I have had my son on this for years due to his anxiety, ocd etc. I will be weening him off immediately. Praying for your child and those who suffer from these terrible movement disorders. We need to make more people aware of this!
