First, BREATHE
This diet is not easy, but the payoff is totally worth it, and YOU are totally worth it!
The hunger is normal in the first week. Your body has to have time to adjust to the diet, detox from the carbs, and start burning fat. Remember that lettuce is unlimited, 2 egg whites are a "freebie" allowed once a day, and often hunger is really thirst in disguise. Drink plenty of water (decaf tea/Mio-flavored water/whatever it takes), and use your freebies. You can also have one hard boiled egg in the beginning if you need to take the edge off.
RE: the veggies - the best advice I can give you is to try new things. I never had a rutabaga or jicama before this diet, but now I love them! It was already mentioned, but LizRR's puree thread is a great resource for veggie purees to get those 2 cups into your meals if you can't just eat raw veggies. The Mix'n in the Kitch'n thread also has a ton of great recipes that use veggies. The important thing is to get your 4 cups a day in, every day.
You CAN do it - and when you feel like you need a boost or have questions, everyone on this board is here for you!
