Has anyone else got sick from using palmolive phosphate free dishwashing detergent?

we got this detergent after moving to our new house. we never had a dishwasher before and I wanted to buy as environmentally friendly as possible. soon after moving in we all started getting very sick. diarrhea and vomiting. it would p and than come back a week later. our 4 year old was the sickest. the doctors couldn't find anything wrong. we were starting to freak out. we made a lot of changes at the same time one of which was switching detergents since it left a chemically tasting residue on everything. i didn't really think that was it, but we stopped getting sick. than recently a friend told us if we used jet dry it wouldn't leave a residue so I bought palmolive phosphate free again. even with the jet dry it left the same residue on everything and we all got sick in the exact same way again. we stopped using it right away and we all got instantly better. what do you guys think. i'll never use that detergent again regardless, but i'm curious to see if this has happened to anyone else.
