First, I hope you haven't given up, and if you have tried cio, you can always re-introduce gentle methods. It's so important that you're following your instincts to take care of your baby's needs and also do what's best for your family. It's really hard not sleeping enough, but baby's early emotional experiences have life-long impact. Speaking from my experience of sleeping no more than 4hrs at a time for 9 months, then baby sleeping through the night at 10m, with no crying (and she's as stubborn as anyone), it feels so good to know that I figured out what she needed and made changes so everyone could sleep better.
Next, it sounds like you might have unrealistic expectations. Can you explain in more detail what you've been doing so people can help you better?
I don't really thing there is any one single no-cry method, and the key is always to make gradual gentle changes. I used Pantley as well as Harvey Karp's recent book on sleep, The Happiest Baby Guide to Great Sleep, and both were really helpful, but you always have to choose what to try at a particular time. Two weeks doesn't sound like long enough to me unless the baby as waiting for the change. I also wonder if maybe you'd get better results (and also lasting, stable results, unlike CIO) if you worked on something "easier" than the pull-off first, and move on to that once you have some progress in another area. Your baby might not be ready to give up feeding to sleep NOW, but he might in a few weeks when things are a little different.
You mentioned he needs to be asleep before you can lay him down - this was one thing I worked on early, following Karp's advice, and I think it helped with the rest of the process. There's more to it than "put them down drowsy but awake" - you sort of have to find what your baby will accept, e.g. mostly asleep then laying down with your arm still around him or your hand on his belly untl he falls asleep, then gradually putting him down earlier and/or doing less. But really, one change at a time, and SLOOOOW incremental changes.
I hope you'll get some more specific advice from people who had/solved issues with the Pantley pull-off, but don't give up! You'll be so glad you didn't!
