6. Prop Up
The same goes for sleeping. If you eat a big meal then go to bed and lie flat, then it should come as no surprise that some unwanted stuff might spill back out and find its way up your pipes!
The solution here is to prop yourself up a little better while you sleep. You can do this by using more pillows and this can also improve your sleep in a number of other ways: reducing the amount of congestion for example. Reducing snoring and more.
Did you know that a few hundred years ago everyone slept sitting up? In fact, it was once believed that sleeping lying down could kill us!
