Cabbage leaves to decrease milk supply?

I’m worried to try this so idk what to do. I have an over supply and I keep getting so much clogged ducts. I take sunflower lecithin daily and it’s not enough to help me out. What can I do to decrease my supply without drying it up? I make abt 50oz of breastmilk daily. I only pump 3x in 24hrs. Idk what else to do. I’ve had mastitis once, and had to fight of a slight fever twice before it lead to mastitis and I’m only 2 months postpartum. I can’t go through clogged ducts like twice a month 😭
