Let this finally END!

Description: I am writing a doctoral thesis, i can't concentrate because i am yawning non-stop. i try to stretch to give my body some pleasure, deluding myself that it will make me not yawn so much, but it doesn't help.in addition, i start to have terrible hiccups, my stomach shakes and my muscles jump. i yawn and at that moment i hiccup. this is unbearable, i will never finish this thesis.
