I often wake up in the mornings with a stuffed nose and I've just started using a neti pot to flush out my nose a couple of times a day. The technique is used in yoga and it involves using the pot to pour luke warm, lightly salted water in one nostril and letting it pour out the other nostril. I've just started doing it so haven't noticed any real benefits yet. Have you ever used a Neti Pot? Did you find it beneficial?
