Fibromyalgia, a cold, a cough and no sun

What do they all have in common?  They all put you right down for the count.  After a week and a half, I finally am coming out of the cold.  The sun is out today and it will be a productive one for me. With Fibromyalgia I cannot function without the sunshine and warm weather.  This last week was a very difficult one.  I am sure all of you fibro sufferers will agree, certain things aggravate the condition and sun deprivation is one of them for sure.  I don't know exactly how I will survive another Wisconsin weather at this rate. At least burning with wood helps warm me a little better.  Anybody else have tips how to deal with cold and dark ole' winter?
