Kim, I believe that Dr. Atkins says to not try to exercise much during the first two weeks of induction.
Everyone is different. My husband got his high energy at the end of day 4. He was an out of control diabetic, though, so just getting his blood sugar under control made him feel so much better, that alone would have increased his energy level.
There is something else you need to consider Kim. You have been under a lot of stress the past week or two. Stress is a huge factor in exhaustion. It may take you a little longer before you notice any improvement.
Hang in there. Don't give up, Okay?
