Try playing with army maintenance at 50%.
In my current game as Granada, I took Andalusia, Toledo, and Murcia as well as the Canary Islands in the initial war. While paying off my 800d war debt I reduced maintenance to 50%, then forgot about it. Later, while I was fighting Morocco, Castile and Portugal DOWed me. After taking Algarve, Azores Diamentina, and an Indonasian TP from Portugal, I turned on Castile and took all their provinces except the capital. It was only after the peace deal that I remembered my maintenance. Talk about patriotic troops- fighting on half pay!
