What I'm doing is a little different so just thought I'd post it as well---
No gluten so no wheat, rye, barley, and only gluten-free oats
No nightshade veggies so no potatoes, peppers, eggplant
No acidic fruits so no tomatoes, lemons, oranges, straw/rasp/black berries
No beef
No or very little caffeine
Very little sugar
Light dairy
As much water as I can drink everyday
This is what is working for me, making a significant difference in my p after just 1 1/2 months.
