Hi alt, well done on keeping track of your food and working out some things that are causing you problems...it's half the battle. I went through something similar when trying to convince my docs I had an allergy to gluten. Took nearly two years to get diagnosed coeliac, but once I was and followed the diet carefully, I felt so much better. I'm hoping things will work out for you once all the tests are over...and then you can start feeling a bit better
Keep going, it does get easier. Hope you're having an ok day.
Bram.
