I had surgery Thursday morning, while on my pre op liguid diet I had no problems. I was not even hungry much! I stuck to it the hole time no problem. Here is the problem I have to be on a clear liguid diet until next Thursday and I feel super hungry!!! I was wondering if it would hurt if I added in a boost or slim fast drink like once a day. All Drs are different that I know. I am eating jello,popscicles and drinking clear liquids...anyone have any suggestions? Thanks
