I'm assuming your feeding him more than once a month now, so my guess was he was pretty hungry before and figured he could maximize his chances for getting food by hunting all the time. But now he is not so hungry he is fine sleeping and digesting. I feel like I only see most of my snakes the day before or the day of feeding day. As long as your temps are ok and humidity is okay you should be okay. You can always post pics of your setup and your temps / humidity too.
