Living with IBS

I was diagnose with IBS since I was 18 years old for a long time I was tolerating it ok even though I visit a lot of doctors and specialties I had a lot of test not very pleasant but I was searching for help with my symptoms that some times they were really bad back then , but all I heard from doctors was well watch what you eat no fat foods no spicy and that was it but I was the same with not much relieve at all.
