I also had a reduction ten years ago and have dealt with similar issues. Definitely check out the BFAR forums, though they are much slower than these here. I never feel letdown when I nurse, and have dealt with extreme nipple pain on latch and vasospasms, all due (I believe) to past nerve damage. But as Meg says, the early days are difficult, even with no prior issues or surgeries. How is your baby's diaper count and growth? You may not actually have low supply; you might just not be responding to the pump. I know I didn't respond to my pump until a few months in.
