This might just be my favorite cure. All you have to do is swallow a spoonful of dry sugar and your hiccups should be cured!!!
Step 2: Drinking from the opposite side of the glass
This one can be a little tricky but once you get the hang of it you'll be using it again and again! First fill a glass with water then place your mouth on the far side of the glass tip your head over and try to drink all the water. Emphasis on "try."
Step 3: Hold Your Breath
This one is really quite simple, just hold your breath for 30 seconds or so then slowly let it out. The picture below is not me it is someone I know.
Step 4: You still have the hiccups!!!
If you have tried all of these and still can't get rid of your hiccups then I can't help. Maybe you should just sign up for Guinness Book of World Records. Who knows, maybe you'll win!
