Re: Oversupply just at night?
Prolactin levels are highest overnight, so it is fairly common to experience higher milk production at that time. I would just stay the course - feeding on demand and nothing else, and eventually your body will get the message to slow down milk production at night. You can use cold compresses or cabbage leaves if the engorgement is really painful, or hand express just enough to be comfortable - but the more you express the longer it will take for your supply to regulate.
Try nursing in a reclined position or side lying at night to slow the flow for your baby.
I had to put towels down under me for months because of leaking. It will get better, though.
