I'm pre-op, but I've had tubal ligation. Best thing ever if you're sure you don't want (more) kids. I wasn't good at remembering and I also wasn't keen on the artificial hormones (pill, IUD, whatever).
Oh, but I did use Implanon (the arm implant) a few years ago (about 10), and that was better than the pill (for me). Also - if you are planning on a family - I don't recommend the Depo Provera injection. The experience I had working in a dr surgery, was that most women who had at some point used it, seemed to have a LOT of difficulty conceiving for a long time after.
