Wow! I am so glad I read this, I had a headache from Day 2 to day 5...Finally I took some Sinus headache medicine, I figured that must be it. now i know, It means something was working. Thank you. I have a quick question also, Today, I had 2 eggs for breakfast ans 4 slices of cheese for lunce. I went to fitday to journal in what I ate, and cannot believe the amount of fat. My mind is telling me it's part of the program, but it scares the heck out of me, and I don't want to weigh myself until I'm on it a week. That'll be Wednesday. Did anyone else get scared by the fat count? Chris
