Maybe you should explore some of the other low carb options under "Which low carb plan is right for me?" (at the right) Maybe one of the other plans would better suit your needs. I tried Atkins for one day-knew I couldn't live with it and tried CAD. After 9 weeks I am still very happy with this WOE. It really depends on your body's needs. If you are always tired-I would listen to my body and make adjustments.
