I talked a doctor friend and he says that it sounds as if I have become hypoglycemic, the symptoms of which can manifest into something that feels like an anxiety attack. He said that he has seen this before in people on Atkins, and while it works well for people with a lot of weight to loose he doesn't recommend it to lose "the last 5 pounds."

I have taken myself completely off the diet and I am going to go in and have bloodwork done this weekend, or sooner if I continue to feel bad.

Thanks to everyone for your well-wishes and concern
