LBS in 11 days - any ideas for pre-op diets that helped?

Good Morning!! Well, please let me first begin by saying THANK YOU!! Thank you for all of you *****sponded to my other post a few days ago on not having insurance and how to go about it. During this process I have met a few of you that have been extremely helpful. To "PAUL" words can not express all your help, thoughtfulness and words of encouragement and what it means to me....thank you from the bottom of my heart from me and my family!! I have surgery in 11 days for the lap-band and I was told that I am to immediately start pre-op diet!  I have started this but was wondering if for any of you going through this right now or having gone through it already have any advice on the food and what helped and didn't help so much. I work long days and am used to drinking my "breakfast pepsi/coke" to get my engine revve'd up to go....so now I am having to stop all pop.....and going straight to water or flavored water and doing a very lite diet (almost diabetic) and keeping to a lot of clear liquids and foods. Well, if you have any ideas.....send them my way please! THANKS! chunky munky
