I have been on Gluten Free diet for about 2 months now, even though I do not have celiac's disease, I am allergic to wheat Yesterday was my sister's birthday and I had the TINIEST piece of cake. Then my husband and I were sooo starved on the way home, we stopped at a hamburger place and I got a hamburger Today, I am TOTALLY exhausted. It is 3:30 and I need to lay down for about 2 hours. I just cannot MOVE. Could this POSSIBly be from my cheating yesterday?? Anyone have a similar experience???
