Today is the first day of Medifast. I have had 3 meals so far. Im not sure you could call them 'meals' It is almost 4 and I have a headache and I am really tired. I am probably going through withdrawl. It is about 80 degrees outside so I think I am going to take a nap under my open window. 13 more days to go. I was told it all gets better by the 3rd day. I am crossing my fingers.
