About ready to throw in the towel

The NUK experiment has not been going well at all. I am this close to breaking down and buying him another NUK. We're going on day ?? (lost track because of minimal sleep). Its getting worse as each day passes instead of better. He just keeps getting crabbier and crabbier and so do we. I'm starting to not care anymore if he sleeps with a NUK until he's 50. Enough is enough. We're giving it one more day...
