a few answers...well, you can cheat as much as you want, but you'll probably lose ketosis for 3-5 days from each cheat...so it's not advisable! I'd go right back to induction levels, yes. (Many of us have to stay at induction levels all the time anyway, so we're already there!)

If your downfall is bread and pasta, then you probably have some sort of grain intolerance. Make a commitment to yourself to stay away from them forever. One little taste will lead to a craving for more. Can there be a life without grains? You bet! You might find a copy of Protein Power LifePlan and read the chapter about grains there, to help convince you.

Make sure you eat enough food--good food like meat, eggs, fish, salad and oils. Try to train yourself out of the "dieter's" mentality that a cheat is best remedied by eating fewer calories or skipping a meal.

I don't buy into the Sommer's concept, so I can't advise you on your meals in particular. Best of luck to you--you have a great start!
