No idea if that would work for others, but my method is simple. When it begins, immediatedly start to suppress it, don't allow the hickup to succeed. Just hold it with all power, don't let it out. Didn't work the first time, the second it's still possible to stop it. After that it's too late to stop it, no strength anymore. Then drink cold water, and swallow it just right before the hickup comes up and after that everytime. Should help well enough, I hope.
