I had my operation 7/3/18. I was not required to have a special diet prior to surgery. I was self-pay. My lab work came back normal/in good health. They also notified me I did not have to take the Magnesium Citrate Oral Solution.
However, I chose to replace some of my meals with soups and liquids a few days prior, and follow as close to a clear liquid diet as I could to mentally prepare myself for the time to come. I had a big burger meal the day before, and then had the magnesium drink and cleared everything. Drank plenty of water and everything went swell
