I think there's something bad in the MN water. I've talked to a lot of women and we all seem to be experiencing similar stomach problems. The only common factor I could figure out is drinking tap water seems to be the trigger for every single one of us. My theory then is there is some strange chemical or bacteria in the water that is disagreeing with our bodies. It doesn't kill us but it does keep us in pain for awhile. Is anyone else in different states experiencing random stomach problems?
