Why is it that when the weather turns bitterly cold that I feel so much worse?

I have no energy whatsoever, no ambition to do anything, feel extremely weak/tired, hot/cold, & hungry all the time no matter what I eat.

Fortunately first thing on Monday morning (1/23) is my last appointment to get the remaining amalgam fillings out of my mouth. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> I am counting down the days!!!!!

How many more days until Summer?
