Take the small packet of Nutella or any other sticky, thick food like peanut butter or cream cheese. 

Place a teaspoon of Nutella in the center of your tongue. 

Place the tip of your tongue on the N point. 

Swallow 2, 3 or 4 times in a row until all the Nutella is gone. 

Repeat this exercise 10 times a day. 

You can use a rubber band to help keep your tongue on the N-point.
