Just saw that you might need a little motivation. :)
How are you feeling today? Be sure to drinks lots of the lemonade as well as water. That tired and cold feeling happens to me also many times on the 2nd and 3rd days. Stick with it! you're almost through the tough part.
I've found that I need to dress warmer during much of the time I'm fasting...though I'm not sure if it's due to more water, less need to cause body heat since I'm not eating as much, lots of cleansing of the bowel and liver so most of the blood is going there or what.
