Altec's carb binge question

[Altec]

I've done Atkins for 7weeks and lost 23lbs. On the end of the 7th week, for 3 days, I ate nothing but oatmeal, bananas, oranges, and brown rice. I stopped because I felt really sick. I was dizzy, weak, have headaches, cold legs and arms, etc. Is this a common symptom to those who suddenly binge? So, I went back to atkins again (induction), and the symptoms minimized. I only have slight headache, and dizziness. How long does the symptoms last?

Is this dangerous? I'm scared.
