Learn to sleep through ANYthing like me
One of our cats was the same way, but once you shut him out, he would howl nonstop. I found him a toy that he absolutely could not resist and that seemed to help when he was frisky in the mornings. (The toy that worked for our little guy, who's also fixed and about the same age, is this hideous fur mouse thing that hangs from a door frame on an elastic string...)
If all else fails, you could get up and feed the guy, because he might just be trying to get you up for food. That is asking for him to stay in that habit though, and is rewarding his bad behavior... so ignore that last bit of advice!
