I didn't have any bad symtoms and I get headaches normally. I did have my am coffee as usual and diet coke, drank some but not even half of the water. I didn't want to reduce caffeine and risk a headache. I was not hungry but I did find after a week that I was not eating enough of the lean because I didn't have a scale. I found one at walmart for under $10. Measure yourself before you start! I didn't do it except for my waist and when I haven't lost weight, I do see a loss in inches. I wish I had measured all over but I was too lazy!
Remember, in the first days if you are having a hard time, have an extra shake, that's fine. And if you have any questions about how to mix something, we'll be here!
PS I just ate onions chopped in pam spray. Yuck! I never eat onions normally but my daughter was making them and they smelled good. My tummy hurts.
I am watching Biggest Loser now and trainer Bob said that the best lunch is a sandwich... it crossed my mind to go back to dieting that way but you know, when I do I take too many this and thats... a bit of this, a bit of that. It doesn't work as well as MF because of the strict structure MF provides.
