Wow, that does sound rough. I certainly had queasy, "not quite right" feelings, but never anything like what you describe. To be fair to atkins, I had even worse stuff years ago when I did the super low fat Ornish bit. Had to drink a few shots of olive oil - my body knew what it wanted. Everybody seems to say, hang in there. So hang in there. After a few days, I felt better than I had in years. So I hope the same for you.
