When my girl was done in January, I had the same problems - she's an extremely energetic dog, never stops if she gets the chance :) She was up and about the day after the op!
I used frozen stuffed kongs (peanut butter + cat biscuit stuffing, or cherrios, or whatever i had really!), and frozen raw bones - they last a good while, and keep the dog entertained. I also used rawhide chews - the thicker white ones, they seem to last longer. Careful with them though, rawhide is fattening!
Otherwise you're just going to have to grin and bear it - it may feel mean, but the quieter you can keep her now, the faster she'll heal, and the sooner she'll be running through the countryside again :)
