You need to take control of the situation. If you need to, shut him in another room - a spare bedroom, maybe the bathroom, making sure there's a litterbox, water and toys in with him to keep him occupied. Him waking you up every hour isn't good for either of you, nor is feeding him "on demand." Pick a time every day, maybe once in the morning, and once at night, to feed him, and that's it! Make it a routine - he'll adjust, and be healthier for both of you!
