Hi, Amy!
First off, I think you probably should see a doctor just to be safe, okay?
However, those feelings certainly could be caused by roller coaster blood sugar as a result of cheating or eating things that aren't allowed. The fact that you are asking if popcorn is allowed tells me that you might not have read the book or read it closely. You shoudn't be eating any starches (that's bread, pasta, grains, potatoes, corn, etc.) or fruits during Phase 1. However, you can have some good carbs like bell peppers, beans, and tomatoes, and eating them can help you avoid the type of symptoms you are describing. Those symptoms usually last as long as the original detox from sugar, which is 3-5 days for most people.
Lack of water can cause the symptoms you are describing--are you drinking at least 64 oz (
not counting soda, crystal light, coffee, etc...) each day?
Like Bamie suggested, you might not be eating enough. Are you getting in at least 1200 calories? Check out what you are eating at
www.fitday.com to calculate calories. Are you eating your snacks too?
Post a couple of menus for us so we can see what's going on, and make sure you read the book. If you have the old hardcover book, make sure you read the updated food lists. You can find lots of important info in the Emergency info for Phase 1 that AdiaFaith compiled.
We're glad you're here...hope you feel better soon!
