I never had anything like this happen to me, but my BIL was having trouble sleeping, and thought is was sleep apnea. One day, on the way to work, my BIL and sister stopped to get a Starbucks, and he asked for soymilk in his. 5 hours in the hospital emergency room, it was diagnosed he had a soy allergy. I am that Royal P.I.T.A. in the grocery store that reads the ingredients labels on everything just to make sure there's no soy, soya, soy lecithin, or even processed in a plant that uses soy in it. Trust me, I reaaaaalllly love Enjoy Life chocolate chips.
