Milk supply

Bobbie
What are some ways to help increase my milk supply? I'm almost 3 weeks PP and was pumping before almost every feeding. I have been drinking a ton of water. The downside is I'm a picky eater and I can't stomach half of the foods that are suggested to help with supply. She usually empties each side when feeding, so there isn't much else to pump. Any mommies have any tips that have helped!?
