Well, as you know feeding a meal that big isn't a great idea due to the possibility of regurgitation. So for now just be sure temps are correct - especially on the warm side because if they get too chilled the chance of regurg increases.
Also, and you probably know this - don't handle the snake at all for several days. At least a week would be best. And try not to stress it with noise, family activity, etc.
I realize all of this sounds a little cautious, and the snake will most likely be fine unless put under stress. I just wanted to outline the most cautious approach. And stick to normal-sized meals in future! Good luck with your chubby little guy.
