Day 4 is always more like days 2 & 3 for me. That feeling of withdrawal is still very much there. Be strong! The excitement you have its so incredibly important at this point of your fast because you are just HOURS from passing over the hump. Use the excitement to pump up your determination and TELL YOURSELF THAT YOU ARE CONTINUING THIS FAST. You are going to find, very soon, a brand new experience awaiting you...where there is no pull towards food, where you become clear mentally, where the fast becomes an unbelievably mindless and effortless task...where the discomforts you feel are not of your body becoming more diseased, but rather from your body becoming more healthy!!
