You said yourself 'he doesn't yell for his binkies or anything - just lost interest b/c the suction doesn't work anymore.' Giving them back would be like giving a person who just quit after 2 years of smoking a cigarette! Binkies are gone, a major milestone in his life, it's time to move on. The worst is more than likely over, you just need to work on teaching him to soothe himself to sleep.
Make sure he's getting plenty of physical exercise running and jumping during the day, and some right before dinner to tire him out. What is his bedtime routine like? Everything should be quieting down after dinner, no TV, no roughhousing, no tickling, nothing to get him keyed up. A warm bath, brushing his teeth, a rubdown with nighttime lotion, a book or two, cuddling, maybe a quiet bedtime song, and down to bed. Make sure his room is darkened so light isn't coming in (we use a shade,) you can run a fan for white noise, and maybe have a CD or radio with soft music playing. The point is to get him relaxed. And does he have a lovey to snuggle with, a stuffed animal or blanket, that he can reach for to give him comfort when you lay him down or when he wakes up in the middle of the night? If not get him one today, let him name it and tell him that when he goes to sleep he can snuggle with it and show him how. My little guy looks forward to going to bed with his bear "Arnold" and his puppy Pillow Pet, "Puppa." BTW, they have smaller versions of the pillow pets now for $12.99 @ Target, really cute for little ones. If he wakes up go in but don't turn the light on, don't pick him up, talk to him quietly, a whisper really, and in a monotone voice, say something like, "It's nighttime, everyone's asleep, time for you to go back to sleep." Give him his lovey, pat his back or tummy a little, but again, don't pick him up, and leave the room. You're trying to teach him to soothe himself to sleep. It will benefit everyone in the longrun.
One more idea that a friend of mine uses for her son since he had trouble going to sleep and staying asleep: she bought a Nightlight Turtle (they come in other animals as well) that projects stars on the ceiling. She said it stays on for about 45 minutes and he falls asleep looking at it, and it's easy for her or her husband to slip back in and turn it on again if he wakes up in the middle of the night.
