Oh poor Jan.

I really know what that feels like-- I also have Raynauds Syndrome-- have had it all my life.
I sleep with thick fuzzy socks on my feet(fins

) from October thru April-- it's so very hard to get to sleep-- sometimes impossible when ones feet are so uncomfortable.
Try some relaxation techniques too-- like-- tensing up your whole body while laying in bed and then letting everything go limp... also try a few slow deep breaths in and out.
Hope this helps some-- sister raynauds sufferer!
