what diet are you following (if any)?
Hi Mia,
It sounds like what you're experiencing may be "yeast die off". A lot of people have a systemic yeast problem, and don't even know it. They feed off the simple sugars that all carbs break down into. I know it's extremely uncomfortable. Honestly, the only thing to do is simply stick with it for a few days. For me, after about three days the craving goes from near mania down to simple desire- but one you can control.
Be sure that you are taking in veggies, and some berries though. You can have half a cup of strawberries for something like 6 carbs, and there is a small fiber reduction that I didn't account for too.
Good luck!
Tammy
