Re: Overactive flow in one breast that won't calm down..
Welcome to the forum and congratulations on the new baby!
Don't worry. You are not doomed to perpetual oversupply. Now that your baby is less interested in eating from the right and is going overnight without nursing, the decrease in milk removal from and stimulation to the right breast is eventually going to cue your body to throttle back on supply on that side. The more you put up with the right breast feeling full, the more you leave milk sitting unused on that side, the faster your body will get the message. And that means avoiding the pump. Every time you pump out the milk on the right, you're telling your body to keep on making the same excess amount of milk. If you want to nurse on the right, try adopting reclined positions; they enlist gravity to slow milk flow and make the baby more comfortable.
It may take a while for this oversupply issue to go away. Managing an oversupply can be a "2 steps forward, 1 step back" kind of process. So you have to be patient!
ETA: I love your screen name! When I had a mammoth oversupply, I often felt like Jessica Rabbit. "I'm not bad, Mr. Valiant. I'm just drawn that way."
