I completely understand because I did the same thing. I started with stage 3 then stage 2 and finally stage 1. 7 months into the diet I still mostly stick to stage 1 foods with a few stage 2 foods. It doesn’t take much for candida to bloom and it can take as long as 6-18 months to fully recover from candida overgrowth.
Eventually you may find that stage 1 works best, I wish you luck on the diet!
There are plenty of great foods to eat during stage 1, like my good old favorite buckwheat! Teff bread is really tasty and I like greek yogurt.
