So sorry about your child,really,that must have been devistating.I think you would really have to talk with your nephrologist or even just your primary doc about this reaction.there could be some connection to the kidneys as in it just does not tolerate the alcohol well or some other bizarre reason.anything else would just be a guess you know?I have polycystic kidney disease and my son has it too but he also ended up with some really bizarre mutated gene from it that actually caused him to go into full liver failure at age 13 and ended up with a new liver out of the deal.Hereditiy is just dandy isn't it?Good luck,Marcia
