My surgery is on the 23rd and I started my preop diet on the 4th, so I've been doing this for a week. My best advice is to stay busy! When you want to eat, go for a walk, drink some water or brush your teeth. Keep at it- you will see the pounds coming off soon if you haven't already! It's only been a week and I lost 13 pounds on this preop diet. I can relate to it being hard, night time is the worst for me so I have been going to bed earlier than usual. But I just wanted to send a note of encouragement that if I can do it, anyone can do it. (I have to admit I cheated and ate something off my diet two days ago, but I got right back on it and it was my only cheat)!
