Okay, so I went and had a frappucchino the other day...
... the following day, I went to the grocery store, and started craving Brussels' Sprouts. Now, never before have I even enjoyed the taste of that vegetable.
That tells you something about how utterly repulsive sugar and coffee must seem to a body that is not used to having them regularly.
I also had this deep sense of need for cauliflower, bell peppers, cilantro, broccoli, spinach and carrots. :P
