Usually getting hiccupy when I laugh is normal for me. Like I laugh hard and every 10 seconds I hiccup. But sometimes I laugh so hard I hiccup hiccup hiccup! It's sometimes the most intense for me, I can hardly breathe. My whole body is hiccupping. My cousin said I should go to the doctor I was hiccupy so much! I I hiccupped for over four hours very severe. But afterward I took a nap and when I woke my hiccups were gone.
