If you have digestive problems, skin problems, mood disorders, or known gluten or other allergies, I highly recommend you repeat Phase 1 on the detox. This will give you a longer period of time to rest the digestive system from all but a few non-allergenic foods.
I also recommend you add another week at the end, to add in more specific foods, one per day (or at least one per meal).
Document what your reactions are. Eliminating foods that are causing your problems for several months or longer as your gut heals will be critical to regaining your health.
