Have been on fodmap diet for 3 weeks although have stopped gluten free bread and just having two rice cakes a day. Pain is unbearable now and are now period pain like, have hardly eaten anything for 2 days as everything seems to be affecting me. Going to my gp tomorrow to ask to go back on ensure as this will give me nutrients as I can't seem to tolerate any food. Has anyone else had to do this? Am seeing my consultant next Tuesday .
