Just hay and water (plus her lick of course) until she is dry and daily checking for full udder. If it feels full and hard ease her out but just a bit.
No greenery, no treats etc, even it this sounds harsh. Once she is dry you can re-start her slowly on concentrate to improve her condition.
Will reply to your pm later tonight, been away at a show at the weekend and while away sheep broke out... but all sorted now. OH is just about talking to me again...
