all you can do is ride it out, took 2 weeks for my supply to dry up.
I've only ever heard of the cabbage leaves in your bra, good luck! :)
Decongestants will dry up your milk supply. Also, for the engorgement fill a tub with warm water and lean over so your breasts are hanging in it. That will help the milk to release without stimulating the milk production.
benadryl will dry u up.... I had a reaction to something i ate turned all red and was swollen and took it with out thinking thank god i didnt dry up.
I did all of those...it takes about two weeks...pump about once a day for like 5 mins to relieve some pressure. I did and it made a big difference...still pretty painful though.
