Hi,
I think you're suppose to try to get some out with a pump or manually, if you feel like that, but only enough so you don't feel pain anymore, not all because your brain will think it now has to produce more. If you do this every time you get engorged, your milk production will decrease gradually once the brain gets the message you don't really need milk anymore and it will stop producing.
With my son I used to pump up to 7 times a day and decrease one pumping at a time but after I did it only once a day, I still had a couple ocassions where I did it every other day until I stop completely.
Good luck!
