One of the frustratingly difficult aspects of training someone to stop hiccuping is that they first need to be hiccuping! So, is there a way to induce hiccups?
Aye, there’s the rub!
I can speak only for myself, but I’ve noticed that after my first sip of a carbonated beverage I often hiccup (but only once, because I realize and stop). It seems more likely with Sprite or 7-Up, but I could be mistaken about that. Have you noticed your own hiccup trigger? If so, please share!
