I know so little, it seems. Well it certainly seems to be a good idea to let go of what wasn't working and move onto something else. I know my mum has tried so many different approaches. She started with gaps, which was the elimination approach and is mostly plant based note now. It seems very similar to what you're working through.
Incidentally, while my main culprit was too much wheat, I find fruit seems to do me good as well. More so than vegetables, even.
