I would avoid the tight bra thing - it's a recipe for mastitis. The cabbage leaves to help. Also consider pumping (infrequently) to relieve engorgement - or nursing her one last time (or 2) on each side will accomplish the same thing.
I've managed to wean my son off of one breast (the "loser" side) but he still nurses 1x/day off the other side. With the one that he's done with, he ate less and less off that side and then we began skipping days. Finally, I went about 4-5 days without nursing him off that side, then did one time, and I haven't nursed him since on that side (it's been 2 weeks now) - I think it's completely done, and I had NO pain or engorgement.
