Jenn, there are a lot of little "tricks" to deal with the hunger. First off, lettuce is unlimited, so you can always eat lettuce with some Walden Farms dressing. I believe you can also have two eggs whites per day - sometimes scrambled egg whites with salt & pepper helps. Then, of course, there's water . . . which doesn't help with the hunger, IMO, but it keeps your mouth busy
.
If your schedule permits it, you might try having your IP packet for lunch, then a couple hours later have your 2 c. veggies, and/or you can split your protein up and have part of it with lunch and the rest with dinner. Some people do better eating small amounts throughout the day, rather than waiting five hours between meals.
Or, take John's approach and just learn to embrace the hunger. It'll come and go while you're on the program.
Oh, and stay away from your scale! As tempting as it is, it's a really inaccurate way to judge your progress, because your weight can fluctuate so much from day to day, and so much from morning to night. You'll just drive yourself crazy if you keep stepping on the scale to "see if this diet is working."
The first couple weeks are the hardest, because everything is so new and you're probably obsessing constantly about the diet
. Just hang in there, and it'll get much, much better!
