The three books in the Culture series I've read just didn't enchant me that much, at least not the way the setting of the Commonwealth did. And in the Commonwealth, you can do just about all of the things you listed, except there aren't that cool of robots, and the making of chemicals in your blood stream isn't there that I noticed, but I'm sure there would be workarounds for that, like certain neural implants and OCtattoos, which can directly effect all the specific-function centers of your brain, including pleasure centers.
