My son very suddenly developed mild facial (rapid blinking eye and lip biting) and vocal tics (sounds like a quiet grunt or throat clearing sound) at a time when I think his hyper/silly behaviour and other food intolerance symptoms escalated, probably in response to his increased consumption of summer fruits, salads and juices. Other symptoms included: loud voice, bed wetting, sinusitis, teeth grinding.  All of his favourite foods were high in salicylates: strawberries, apricots, rockmelon, tomato, cucumber, capsicum, broccoli, vegemite, spag bol, apple juice etc.  His diet contained few foods with colourings, flavourings and preservatives as I've always tried to encourage "healthy" foods which he has been very willing to eat.

We noticed some improvement (in behaviour, bed wetting, teeth grinding but not tics) over a week just by changing fruits to pears and bananas, stopping vegemite and tomatoes and switching to low sal veges and Bakers Delight bread.  We visited a dietitian and Joe (not his real name) started on the elimination diet. He had a very obvious reaction to sals - hyper like I've never seen him within about 4 hours of starting the challenge.  I wouldn't have believed it but my parents witnessed the reaction too!  When they visited, he was his usual self, undertaking some quiet activities requiring concentration (jigsaw puzzles, colouring etc), chatting and on his (usual) best behaviour.  Within about an hour and half of their arrival he changed into this wild, racing, hyper thing heart racing, unable to stand still, almost a "mad" look in his eyes, silly silly silly etc...the worst of it finished within about two hours and he basically collapsed exhausted and couldn't even stay up to wait for dinner guests that he had been looking forward to seeing.  Very strange but so similar to the stories I've read on your web site.

We didn't manage any other challenges before Christmas - felt it too unfair to restrict his diet so severely during the holidays, although I did continue to restrict sals and he doesn't eat many processed, flavoured or coloured foods anyway.  We continued along on this basis, watching his sals intake over a day and over a week, and the tic went completely. His behaviour was much more predictable and stable and very much like the boy I know.  He is still bed wetting although I am convinced it is worse when he has had sals (e.g. salad) in his dinner and this seems to be improving, particularly since we have been focussing consistently on his sals intake. Teeth grinding and sinusitis very improved. So I am absolutely committed to continuing our new approach to Joe's diet as we really have seen some big improvements. - by emails over a period of 3 months
