Hiccups and Yawning

I haven't gotten hiccups in a long time, but I had a long bout of strong ones come on all of a sudden! I also can't stop yawning, because they keep getting interrupted with hiccups. I'm just not able to satisfy that urge to yawn. I hiccup for over 10 minutes, while trying to distract myself on the computer and on my phone, but these hiccups are so intense they make my eyes water. They just don't want to stop.
