I don't actually DO failsafe, but I do follow it loosely, as DS reacts to alot of things. He is definitely salicylate sensitive, and reacts to a few additives (so I try to avoid as many as possible). Yes, it is time consuming, but it does get easier as time goes on. I would say it takes awhile though, at least 6 months before the new stuff becomes 'normal'. Very worthwhile though, for us anyway.

I have no idea is 160b is in flavoured milks, because we can't have milk , but it should definitely be listed if it is an ingredient.
