a couple ideas

for some insane reason i live in the cold north. when i juice fast i can get chilled. two things that help are plenty of hot hot herb tea. this will keep your body temp up. it also gives you an excuse to make some really awesome super healthy and tasty herbal tea mixes. also the iimportant thing is to keep your body temp up consistently, once a chill sets in it can be hard to get temps back up. try to take a hot bath if a chill sets in. also at night get the largest mason jar you have, fill it with boiling hot water, cap it tight, wrap a shirt around it and take it to bed with you. the heat will be slowly released all night and keep you toasty warm.
