I have found that things I thought were safe for me to eat, and always had been, will one day up and give me a flare. It seems that nothing is ever safe all the time. I am in the same boat as you btw. I have eaten very little in the past 9 days.
I suggest you take another look at your diet. I have had Ensure give me flares too.
