Hi , I have been on the pre-diet for 7 days now. My surgery is next Thursday, and I am going through a lot of emotions right now. The first 3 days of the diet in the later afternoon and evening were the most difficult. I am able to drink herbal tea on my diet so that has helped when I feel really hungry. I also have a horrible cold I am getting over right now, so I have not been as hungry as usual. Keeping as busy as I can has helped keep my mind off food. Looking towards the future is worth the effort of getting past this part. This time will go quickly and you will get past it, and be proud you did it. Hang in there , you can do this.
