Hi Davit and Teebs: It took a couple of times to get the real hang of it, but basically you do it over your sink with head tilted to one side - then switch over to the other side for the other nostril. You do feel a bit of pressure in the sinus cavity, but doesn't hurt at all. The water goes in one nostril and out the other, washing away any pollens, dust, etc. Doesn't take long and right away you feel cleared up and can breathe. You only do it once a day. When you buy the neti pot you get little packages of solution to mix with warm water. All the instructions are there and easily understood. Most pharmacies have it and Walmart has it, not expensive and you can buy packages of solution later without having to buy the neti pot again. Good luck.
