I've had an issue with serious hiccups since I was a ***. But this remedy which was handed down from my grandma has worked for me each time: take 7 sips of water (why 7 and why water? nevermind) then inhale deeply and hold your breath for as long as you can. I always use that as a last resort because it's cheesy af, but it's always worked.
thanks grandma!
