First Hiccup in Years, Can't Stop

This is the first unstoppable hiccup for years! I usually can quickly stop hiccups, but this time is unbearable! I make some weird sounds with my throat, the belly is shaking, my head is dizzy and I'm even not feeling well. I'm trying to stop it like I always do, but nothing works! Finally I am able to stop it with simple holding my breath and moving my diaphragm/belly. Whoo, now it's feeling better, I can breathe
