I have been experiencing a problem with yawning for the past 3 months. As i reach the peak of my yawn, it suddenly goes away, leaving me with the unsatisying feeling of not being able to complete a yawn. Sometimes i feel like i have successfully completed a yawn but then i know i havent because another yawn comes back 10 seconds later and it happens over and over. Its very frustrating and i really can use any advice or tips on how to stop this. Anything can help. Thanks!
