Get a bag of the think plastic 'sandwich maker" gloves at the dollar store and a jar of a powerful moisturizer like Eucerin or Bag Balm. At bedtime, put a lot of the moisturizer on your hands and put on the gloves to keep the moisturizer from getting on everything. Go to bed. In the morning, take off the gloves and wipe off the left-over moisturizer. Your hands will stay soft and less itchy all day.
