New start 4 Posted September 30, 2011 So I am one step closer to the 13th!!! I was very surprised my Dr did not require a 2 week pre-op fast, only clears the day before. He said the pre-op 10 % wt loss requirement was enough. Also he does not require post-op B12. Does this sound strange to anyone? One last question. With the restricted volume and high Protein, is anyone eles having trouble getting in enough potassium? I saw a post about using Powerade zero which I have tried, but I retained so much Water fronm the sodium. What am I doing wrong? Share this post Link to post Share on other sites
