(Heres a little fact about
yawns, theres many reasons people
yawn, but the medical reason is, its our bodys function to trying to get more oxygen, because we don't have enough oxygen) By breathing through your nose, you get more oxygen, and through your mouth, less. So if you are constantly breathing through your mouth, you are only hurting yourself, believe me, it will come, just relax and take breaths through your nose.
