I think I figured it out - my energy reversed itself the afternoon of day 27 (that part I did not figure out), then i started having stomach pain all day on day 29 - as soon as I woke up I felt it - like my colon was inflamed. the pain lasted all day. I was mainly concerned with getting my energy back up at that time and checked the forum about that on day 29 and thought i needed to be eating a little sweet potato at each meal and it did get my energy back up. then after day 30 but before i reintroduced anything, stomach pain came back worse. so i checked forum on stomach pain and found a lot of posts of people having stomach pain. I spent most of the rest of yesterday figuring out what I needed to do - my pharmacist did not know what a digestive enzyme was except for dairy intolerance (he did NOT understand that I didnt need that becuase i had not had dairy in over 30 days!) and did not have any digestive enzymes so that is not readily available for me to take, but i did start a probiotic yesterday and studied the fodmap. Seems that since I cut out the sugar, grain, dairy, gluten I was depending on some high fodmap foods that I usually eat sparingly - sweet potatoes, cherries, bananas and it has caused me to have bad stomach pain if I eat anything high fodmap (or too much low fodmap which is the sweet potato).
