Hi!
I'm kind of new here, but I would just like to encourage all the beginners...A week is behind me and I almost gave up - I was tired, hungry, had no energy for anything....I was thinking this isn't for me, because most of women here were saying it takes 3-4 days to feel better...
Well, it took me a week and really, it IS worth it!!!!
Try to distract yourself from food. I know it's hard, you might not have a lot of energy for doing things, but maybe -read, study... -study is what helped me. I was really busy last few days and now I don't even get hungry anymore. I have to remind myself it's time to eat!
