I have a cure that works EVERY time. However it's illegal and I think you're a good girl so bad luck. But you do have 100% sympathy - I get it occaisionally - been a few years now - it's very funny for everyone else, but no joke when you're the one in pain. The cure starts with ha and ends with shish. Relaxs your whatsit immediately. I had a friend from Sierra Leone who was prescribed it along with a small pipe for asthma - not the first thing that springs to mind is it? But it does work, and probably better for you than an inhaler...
i get the hickups a LOT .... I always hold my breath to re regulate the breathing ... it does work but can take time ...
