Welcome to our world!! Seems every year about this time we have a flood of threads from that year's class expressing the same problem. Yup, it affects us all. We used to be able to hibernate comfortably all winter long. (Of course, the flip side was that in warm weather we'd be dripping sweat just thinking about hoisting ourselves out of a chair!

)
Snuggies, blankets, sweaters, logger's socks and just about anything made of heavy wool are all strategies we use now that we've lost our thermal layers. You get used to it, and I doubt you'd trade the inconvenience and discomfort for how you were last winter!
Bundle up, and be glad you live in the warm part of the state. If you were in the Tri-Cities or Spokane you'd really be hurting! In a few months, maybe you can spare a tear for those of us out here on the wide-open northern plains!!
