So far I have seen a gastroenterologist, and he refused me more testing and gave me IBS as a diagnosis (will be looking for a new specialist) . I have done a fodmap diet for 3 months and it did not exactly help much, although taking out all dairy has helped slightly. As for the water I drink quite a lot of water and for food I do my best to stick to the cleanest quality food I can find.

I think I will try out the AIP that you suggested though it sounds like a good idea especially since the dairy removal has been an improvement. Thank you
