I had hiccups for 4 days an orange or a few grapes would stop them for a few hours. So I starting eating 4 or five grapes as soon as the hiccups would start again after 2 days of eating grapes they stopped. I have been eating a few grapes and an orange most every day for two weeks and they have not come back, I don't want to go through that again, couldn't sleep, had really bad heartburn and was getting sore from strong hiccups.
by the way I tried drinking water upside down, holding breath while drinking etc. Hiccups never even slowed.Hope no one else goes thru hiccups that bad , but if you do I hope this helps.
Hiccups, Whenever I get a case of the hiccups I usually eat grapes! Red, green, black. It works! Just eat three or four grapes, its gotta be something in the skins!
