brain, one good thing about gypcrete is that its fairly easy to remove. start by drilling some holes in a 1 ft sq area(like swiss cheese), then get a chisel about 1 ft long or so and chisel up that area. next chisel between subfloor and gypcrete at a low angle, pound in a couple of inches and lift!
