Don’t Lie Down

That means no naps (unless you can do it standing up). First, you lose the chance to burn off some of those calories you just ate by, say, doing the dishes or going for a walk. Also, when you lie down with a full stomach, food can work its way back up. This can slow digestion and worsen acid reflux (GERD). The couch will have to wait until your food has time to settle.
