welcome Jasmine
my son is adult now, dx with TS when he was 10
He has had great success following a nutritional treatment plan, that I have documented here

Most people who try natural treatments for TS have found increasing their magnesium intake to really help with their tics. There is research to support this by Bonnie Grimaldi, who has developed her own supplement line after the success her child, and many others had with her protocol

If you are interested in natural treatments, there is also a very helpful reference book here
