I generally have an iron stomach, but if the hiccups come, there is only one solution.
Probably twice a month. The only way to get rid of them is to force myself to puke violently. Feel like a million bucks afterwards though.
Last time I puked involuntarily while drinking was like 1996 new years. Was a veggie at the time and somebody tricked me into eating some pizza with meat on it. Didn't sit well. My first hour of 1997 was spent puking in the bushes by the front porch. Not my porch.
Only time I've been on LI for the record.
