Since June of 2014, I have had a problem
yawning. Whenever I feel a yawn coming on, I open my mouth, and when I reach the peak of my yawn, it suddenly goes away leaving me unsatisfied. Then, this happens about every 10 seconds until something comes around to get my mind off of it. This has been happening since June. This is the main problem, but since around then as well, I have some kind of post nasal drip issue going on.
