Giving up coffee was pretty tough for me. I went cold turkey on coffee the same week I went strict paleo. It was brutal. I think the caffeine withdrawals were much worse for me than the carb flu. It took me two weeks of headaches and a pissed off attitiude to really let go of coffee. Nowadays I will drink 1 cup of decaf coffee but I am not quite as addicted and use it as a crutch to wake up in the morning. I do sleep much better now without all the caffeine.

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
