Mittens...
and to be honest...I know it sounds silly but when you feel the need to scratch, tell someone to slap you if you scratch, it'll put you off scratching more cos the more you scratch, the itchier it gets.
Ummm...as Andy says, cut dairy products, some people find that's what makes it so much harder. My friend's just cut out dairy products about 2 months ago as she has extremely bad eczema. It's been a lot better ever since and she only has it on the inside of her right arm now. It's also made her feel a lot better in herself so yeah, it might be worth a go.
