tourette's syndrome
"My son was having severe motor and vocal tics (30 per minute). It was horribly scary for us all.  He already had been diagnosed with ADHD and was taking guanfacine. Upping the guanfacine dose did not help so they prescribed clonidine for the tics. At first it seemed not to work at all although it did help him sleep because he could not sleep due to the tics. But the MD upped the dose and we waited for the meds to kick in (can take 2-4 weeks!) His tics have almost completely stopped! He is back in school and back to a normal life thanks to God and clonidine. I recommend giving this medicine time to work.  ALSO, it still makes him very sleepy for about 2-3 hours after each dose. We manage this by dosing him at times when he could sleep after."
