Bluebelle, My second daughter is like you. Always cold, she is enjoying a happy comfortable week now. Always said she should have lived in the Tropics. She was using her electric blanket still, each night, upto about four or five weeks ago!!!
Very bravely, she announced at the beginning of this week that she was going to try to NOT use her summer duvet one night - but gave that up half way through that night!!
Her hubbie is the opposite and uses just a coverlet (no duvet) most of the year. Fortunately, their 6 foot electric bed permits then to have these different heat zones!!!
Last evening she visited me, and I had to stop the fans oscellating in her direction as they made her too cold!!!!
