I think the secret to success is finding creative ways to use the packets and changing up your daily vegetables and meats/fish. Sure, they're fine for the first few weeks, but after that you're going to want to introduce more variety.
Check out the threads about recipes and alternatives (if your IP coach allows you to introduce them, especially if they have difficulty with supply of certain popular packets). The other place I get ideas for non-IP meals (lunch and dinner) are on the "What are you eating today" threads. Some of the meals are truly ingenious and/or inspired.
As others have said ... try not to look at the bigger picture. Concentrate on today, and do hop on over to the Daily chat. Hopefully losing the weight and inches will give you an "oomph" start and get you focused.
