Why are you still night feeding? After the first month children no longer need night feedings, they only do it because we train them to, in fact my doctor told me there was no need for night feedings after the first 2 weeks of life. I would stop breast feeding altogether, that is the only way you will dry out. To ease the discomfort take a warm shower or use a warm compress to help you express a small amount to ease discomfort without having to draw it out (by sucking or pumping which will continue to stimulate production).
