If you are serious about getting chills, no worries! This is just a function of fear leaving your body! I've had times lately that I would spontaneously become so icy cold that I would begin to feel hot! Although it is not the most comfortable feeling, just work with it as best you can and know that it will pass! Just remember to stay as warm and comfortable as you possibly can; wear soft clothing and baby your senses! If you allow yourself to relax into it, it's actually quite fascinating and a lot of fun, lol!
