another thing to remember is to reduce your fluid intake. When you are starting out breastfeeding you have to up your water intake so much and when you are stopping you have to do the opposit. A bit tough when the weather is warming up but it did help me. Also cold flanels/cold showers to help take some of the soreness away and avoiding hot showers & baths as is brings the milk down faster!
Basically everything you did to increase your supply at the start but in reverse
