I've never had that happen...because I never go anywhere (
) haha but I do know that when I don't have a lot to do, I get bored and go back to my eating when I'm bored routine. Maybe since you're back home, you feel comfortable and in a routine that makes you feel like eating more.
When you feel like eating, wait 10 minutes, drink a glass of water, and then in 10 minutes if you're still hungry have a little snack. Sometimes it's just thinking you're hungry and the water or the time will make you feel better.
