Susan,
Sometimes,if that stomach "ooginess" won't leave I have a few days of totally bland food to start afresh.
My body seems to like the scrambled eggs and lack of of food additives.
At this time of year my ragweed allergy kicks in some other odd food
alerts ,especially to sweeteners like aspartame.
Once the first frost has come and gone,I am fine again.I hope you feel totally better soon.
