The 1st 3 days are the hardest. Your body goes through withdrawal of caffeine, sugar, fats, etc. My husband did the diet with me to show his support and did not experience near what I went through. I actually felt so bad day 3 that i called in sick. After the 3 days I wasn't stomach hungry as long as I drank my Protein shakes, I was head hungry from time to time. I also went through liking the shakes the first day and not liking them on day 2 and 3 (made me nauseous), then day 4 I was able to drink them again by changing to a different flavor. The whole process took me by surprise. I had lost so much sleep prior to starting the diet about not eating for 2 weeks and I didn't think it was that bad after I got past the first 3 days. I'm proud to say that I did not cheat once.
Stay ahead of your hunger and eat so you do not get so hungry that you cheat. It is important to take your diet stuff with you to work and eat or drink something often (obviously staying within your diet guidelines) and drink Water, water, water because this helps you stay full and helps flush out your liver. I dont know if you have ever had surgery, so this advice also goes for pain. Don't wait for the pain to start coming, get pain medicine before you feel it. If you stay ahead of it by taking it even if you don't yet feel the pain, you will reduce your discomfort tremendously. I hope this all helped. Good luck to you!
