It’s pretty amazing that you feel so terrific so soon! Really, it takes most people a few more than that to really notice much. So, that’s a lot to be glad for. If I were you, I’d be more convinced (not less) that your issues are candida related if you’ve seen an improvement on the diet. If your symptoms have been hanging on for years, you may need to stay in Stage 1 longer than the 3 weeks recommended. I didn’t really feel a tremendous change until week 6, for instance.
If you’d like to know about your tongue for certain, you could always have a doctor’s office culture it for you. They’d be able to tell you if it’s thrush. If it is, then you have yet another symptom that’s directly connected to candida without a doubt.
Seems like the diet can only do you good at this point! And this is a great place for support & info 🙂
