If you feel WORSE on Heather's diet...get tested for celiac. Heather's diet made me worse because I was eating gluten. Now I am gluten free AND doing Heather's diet and I feel GOOD.
I've had IBS since I was FIVE btw. I found Heather's diet after over 18 years of searching! Be thankful you found her at 21...
You will get better...if you want to and you try. There are people on here who have suffered for YEARS. Myself included. It has taken me since I was FIVE to learn I have a problem with gluten and I'm 26 now. I also have other illnesses as well. And I was sticking to Heather's diet and being patient and I STILL suffered because I had the wrong diagnosis.
