I was feeling quite lethargic (not to mention extremely grumpy) today.

It’s probably because of the changes I’ve made on my diet. Since last week, I’ve opted to follow one of Bob Greene’s golden diet rule of not eating after 7:00PM. My body is still getting used to eating a bigger breakfast and a smaller dinner meal.

Ever since then I’ve been on this state of constant,unexplainable hunger. It’s the most weirdest thing.
