dumping on string cheese?
My guess is it might be the same as it is for me after sticking to an all liquid diet, when I eat something solid-- no matter what the heck it is-- I get instant diarreah and it lasts for hours, or a whole day, even.
It is just the body saying, "What are you doing? First you give me only liquids, now you want me to digest solid food?" Quite normal, if you check websites about fasting, like curezone.com.
For me, anyway.
