Well, I had a more productive flush today. The grey salt is much easier to drink - thanks.
However, I went to the doctor today for an unrelated issue, and asked her about the diet. I know she's pretty open minded about medicine, herself, judging by some of the things she's recommended to me, but this diet was something she didn't like the sounds of. She said that I'm not be getting enough electrolytes, especially with all the sodium I'm drinking, and that lack of electrolytes can cause heart palpitations, which can lead to blood clots, which can possibly lead to death. SO...I'm getting off the diet today. She did recommend cleansing, but a different approach - herbs. I may try that after I get my stomach re-acclimated to food. Thanks for all the support and advice.
