What you are experiencing is not that out of the ordinary, although feeling like you were going to pass out is of concern. I would slow down your transition to a sugar-free life by first eliminating all obvious sugar (soda, cookies, cakes…) and see how it goes. From there, you can move to eliminating foods that act like sugar.

If you have cravings for bananas and sweet potatoes, I would say go ahead and eat them, even though there are fairly high on the glycemic index. The most important thing is to continue to breast feed.

Any thoughts? Also, as a side note, I really crave bananas, sweet potatoes, etc and I have not previously even liked these foods.
