We used PU/PD to break our 2-3-times-a-night wakings, nursing back to sleep at 9 months, and it definitely worked! S(Seems to me 9 months is a critical period for sleep issues!) I will warn you, though, it's really tough and it only works if you see it through. But if you stick to the plan, it will work!
I definitel had help from DH, who did the PU/PD at night for the first bit, but I did it during the day, for naps, so it will still work-- it will just be harder because you are the milk machine. Can your DH not understand that you can not be getting up twice a night to nurse for the forseeable future? I'm with Jodie, I think I'd be less inclined to be in such good humor about this...
