Go for it is right! I did my first flush last night! I did not stick to the no fat day yesterday. I made a vegetable fritata for "brunch" for my family and I did fine. I feel great,I had no discomfort. Just clear the path between you and your bathroom between this evening and tomorrow morning! I also was afraid, but now I am ready for my next one! I am estimating I got out approx 2000 stones. Got to go to work now so.. .Good Luck...you'll be fine!
