My doc suggested the following, but not vegan: cut out or very limited sugar, dairy, caffeine (I have 1 cup of coffee a day then chamille tea), limited alcohol, decrease spicy and fried foods. Make sure you hydrate well every day (at least 1 gallon), ensure you are consuming fiber, get your sleep and seriously decrease your stress level. All this has worked for me since diagnosis in February. I had one flare since then that landed me in the ER again in June, but that was before my adjusted meds regime.
