You will be fine! Being 6'2" 384 pounds, believe me when I say that I thought there was no way I was going to complete a 14day pre op liquid ONLY diet. I bought shakes, Gatorade, etc, etc and I did not look back. Like people stated in other threads, after the third day, I didn't focus on not eating, but just drinking my shakes, Water etc on my schedule. My body told me when I was hungry and I had a drink. Jello and Popsicles were/are great and helped me.
The days leading up to surgery, there was one moment were I almost lost it and wanted to give up. I had told friends, coworkers and family that I was having surgery and I thought what if I failed, what if I eat the wrong thing, what if the weight don't fall off? But then I heard a whisper that said, look at how far I have brought you.. In your pre-op diet, you lost 14 pounds. You are already doing great! He is in control and you will do just fine. Use the tool and I will see you at your goal line!
My surgery was on 4/1. After coming home, I was weighing myself daily, but I had to stop. I will weigh myself again on Monday, but I do know the last weigh in was 355 which is 29 pounds down.
You can do it!
