Induction should really be done clean with only the foods on the acceptable list, ESPECIALLY if you have problems with cravings and have found you have problems losing and sticking to the diet.

It's only 2 weeks. While grains are one of the last things to be added on the carb ladder, the tortillas are probably high enough fiber to add earlier IF they don't cause cravings. If you find you're having cravings or can't stop at just one, leave them alone till maintanance.

Sticking to the plan will work best. Some people can add things back in and still lose at a great weight, but you complained before that you were having alot of problems losing and sticking to the plan.
