Seriously, just a PSA about getting rid of the hiccups. This method works perfectly for me. It is not an exaggeration to say it has been life-changing. Hiccups gone immediately every time.
I used to do this sort of zen thing where I would just sit quietly and concentrate on breathing steadily. It sorta worked, or at least, I was able to wait it out. Then for some reason it stopped working in the last few years and I started doing this instead. This is way better anyway.
