Hi, and great job. You can stay on induction as long as you want, but Dr. A. wrote the plan for induction to give you a kick start. I think you might be a little confused about OWL. With OWL you still keep your carbs very low but you do add different choices slowly. It never means yes, I can eat a bag of chips.
I would not recommend cheating with Atkins. Once you eat that bread you might not be able to stop, and your cravings will come back. Try adding something with more carbs but still on plan.
You ARE allowed yogurt on OWL. Look for low carb diabetic yogurt, or plain greek yogurt. You are also allowed berries. But don't add them all at once. Choose one thing you want to add, then wait to see what the outcome is before adding something else.
If you can get the Atkins book out of the library it might explain it much better than me.
Keep up the good work. And I thank your husband for his service and sacrifice.
