Reoccuring hiccups?

I get them twice, sometimes three times a hours of daylight. And they get so, so annoying! I'm not worried, but does anyone know why this could be scheduled? I know what CAUSES hiccups, so you don't need to explain that, but anyone know why I'm getting them so habitually? I have asthma, so could that contribute to it? And do you know of any pious way to gain rid of them? Right now I hold my breath and drink hose at the same time, but I'm not well brought-up at holding my breath... any other way?
Thanks!Reoccuring hiccups?
