I've read your post and couldn't believe my eyes. I am on day 6, first week and I still feel dreadful. I have a headache every day, no energy and just feel ill with weakness. I had been following a low calorie diet before LLL (i am on the lite program) and am not that over weight, want to lose a stone but to be in the healthy range i would only need to lose a few pounds. Please tell me someone else felt like this??! All I hear is that everyone else has energy and feels great! This is good for you of course but I would like to know that this will go away and I'll feel like you soon. I'm not particularly hungry and it's not that i'm craving to eat stuff I just feel very light headed all the time and weak. Thanks for any responses.
