Oh man. I fucking hate fucking hiccups. I get the hurty ones, too. I get the ones that keep coming back all day. And I have athsma, so sometimes they trigger an athsma flare. Fun fun fun.
So - the sugar thing sometimes works for me. But I don’t eat the whole spoonful dry, I just keep eating it until it’s gone - but no breathing in until it’s gone. Same thing for honey. The trick is no inhalation while you focus on the sweet stuff.
Water fountain. Ten big gulps of water, no breathing in. Sometimes I can only do seven or eight before I have to breathe, but mix a lot of air in with the water you’re slurping. Not delicate, not pretty. Sometimes I can tell it dodn’t work and do it again. Usually results in large belch, which is the end of the hiccups for the time being. Often the water method needs to be repeated as it does not prevent recurrance.
Water in a cup. Big cup, not more than 2/3 full. Bend over, drink from the rim furthest away from you, big slurpy drinks. No breathing. Stand back up, belch.
Use athsma inhaler. Only if you have one, and doesn’t really work anyway. But sometimes you’re just deperate.
Hold your breath. Doesn’t usually do shit, but if you’re trapped on a bus or in a meeting or something, it passes the time and keeps your mouth shut so the hiccups aren’t so loud.
Breathe in to a paper bag. Now you’re really getting desperate. It’s 2 in the morning and the hiccups have woken you up. You’ve tried all the water and not breathing shit, that didn’t help. Try hyperventilating. Works occasionally.
Desperate measures. Last resort. It’s 3 in the morning, been through the whole bag of tricks. Feeling frenzied. Stomach hurts from so much water and sugar and honey. Punch self in diaphragm. Repeat. Not recommended. REALLY not recommended. Works occasionally.
Getting frightened actually does work, the whole jolt of adrenaline. But it takes a lot of skill and luck to startle someone who has hiccups. Usually they are just annoyed. Sadly, orgasm does not seem to work, but it can be fun to try.
