Hiccups: Spasms of both the vocal cords and diaphragm, causing periodic, audible, short, inhaled coughs.
Causes: Irritation of the diaphragm, indigestion, or your habit of drinking and eating so fast.
Self-Care Treatment: Breathing into a paper bag (inhaling carbon dioxide) or dissloving a teaspoon of dry sugar at the back of your tongue may stop them.
Personally, breathing into a paper bag works for me. Whenever I can't help getting hiccups, I breath into a paper bag for 10-15 times. It works!
