I am thinking I am experiencing the Induction flu. I looked it up and I found out that this is normal and it is temporary. It is basically like I am withdrawing from sugars like an addict withdraws from drugs. It is actually a good sign that my body is reacting to this change in diet and I will feel better once I get acclimated to this way of eating.
At the beginning of induction phase, you will be withdrawing from sugar and caffeine. For these substances to leave your system, it may takes around 3 to 7 days. During this period, you may find that withdrawal from these substances causes you to have nausea, headaches, "brain fog" , diarrhea, and muscle cramps. This is also known as "induction flu." If you suffer from these symptoms take heart- they are very temporary. Soon, you will wake up fresher and more energetic than you’ve had in years, your moods will stabilize, and your hunger will disappear.
