Day 3 is the hardest day of all for most of us! My headache came back, with a vengeance; but I know it'll disappear and take a lot with it! As for stopping on Day 5, that would be an accomplishment. However, at that point, you'll have most of the rough stuff behind you. Your body will be in fine cleansing condition. The last 5 of a 10 day are definitely the easiest and the most beneficial. Try to stick it out. What are 10 days out of our lives? Especially when they may give us more days in the long run? Or at least better health to enjoy! You CAN do this. You DESERVE to do this for yourself!
