Hi I am having my sleeve next Wednesday and my doc has me on a preop diet of smaller portions of things like cottage cheese, chicken and corn... I didn't realize how important it was until I read some of the articles. I haven't been very good about it.. Am I screwed!?! Also one of my family members googled my dr and it looks like my doc has had a few people make bad comments! When I researched her before and I had some feedback from a nutrition class that she was a good surgeon... Does anyone have any knowledge of dr Valerie Halpin from Oregon?
