Does anyone get a bad taste in their mouth with their ibs. I am having symptoms later in the day I assume as a result of eating of slight nausea, stomach discomfort and bad taste in mouth. I saw somewhere that brushing your tongue as well as your teeth can help and this does seem to be true to a certain extent, although it doesn't go completely. It makes me feel very uncomfortable. Any suggestions. Sticking mainly to low fodmaps diet..
