and you get to come to this great forum in support of each other to talk about fasting and just feeling like a fatty. hardships faced in numbers become very soft!
read all the rec. messages to make yourself comfortable.
and dont forget to listen to YOUR body when it comes to fasting. it is different for everyone. know your limits and know the risks. but most of all know that you should feel good because you are doing something to improve your health that most people couldnt do.
