Maybe it's the carbohydrates and the
Sugar in the yogurt that are making you sick... how many carbs are in there? My guess is its probobly pretty high...
Try stonyfield farms organic PLAIN yogurt, no added fruit :) if that does not work then maybe yogurt is not for you.
From what I have read some people have a problem with yogurt and since you are so sensitive maybe you can't do it.
