I had oversupply with my first, and I decided to try to stop it before it happened with this baby. So far so good, though baby is only 13 days old. I am block-feeding, not by a strict schedule, but just trying to feed first on the emptier side. This is what worked with my first to eventually stop oversupply as well. I am also using Lilypads (sp?), which are these silicone things you stick over the nipple. They stop leaks, and they are also supposed to help with oversupply. I like them a lot so far.
