I've heard frozen cabbage leaves on your boobs will help.
From my understanding, there is medicine to help shorten the length that milk is produced and help you dry up faster. Definitely talk to your Dr or inquire at hospital. Best of luck!
I noticed when I was shopping the other day that Earth Mama Angel Baby makes a tea to dry up your milk. I think it's called No More Milk. I haven't tried it but their other products seem to work really well so I would think that one would too :)
They should give you a shot after you give birth to prevent milk from coming in... if not, you can take anything that clears up the sinuses (like advil cold and sinus or something similar)
Cabbage leaves in your bra, will actually draw it out...and help you dry up quickly
Maybe you can speak to a lactation nurse (unless u did in past already) and tell her your concerns about breastfeeding, if you'd want to give it a final shot.
My dr told me they dont give medicine to dry you up or prevent milk because it was causeing brain hemraging (sp) he said it isnt aloud anymore.. :/ but he said wearing a tight sports bra, frozen cabbage, and starting my burth control pills imeaditly after birth should help dry you up quickly! Hope that helps!! :)
