Awww...I can sympathize with you. When I got Scottie at 5 months, I lost about 3 months of sleep. I chose the crate training method and it was not easy, but it was worth it!
Poor you, I wouldn't want to sleep in the kitchen either! It's time for you to take the reins and not let him be your boss.
I'd also suggest to tire him out before the end of the night. That may help?
