mandyleigh, lots of chicks report experiencing the appetite suppression. I know it happened to me, and boy was I surprised. I have never been disinterested in food. It's important to make sure you keep eating, I was tracking my calories when I went through this, and some days I was logging 800 - 1000 calories, so I would add an extra bedtime snack. Too low is not good. You don't have to track calories, but just beware of the temptation to take advantage of no appetite and lose a few extra. You don't have to force feed yourself, just keep up the healthy nibbles.
When you start Ph2, and add back some healthy carbs, you should get your appetite back.
Life's a journey, not a destination.
It's easier to stay on plan than to get back on plan.
