Hi, This is my first post. I have my surgery next Tuesday @ 1:30 p.m. and will spend the night in the Tucson hospital, that is, IF I can get my sodium levels up. At my pre-op, I was told to go home and eat pretzels, drink GadorAid or the like and NO water as it will flush sodium out. I go back to the Lab on Saturday for another blood draw. Wish me luck.
