Hiccups and taking pills?

Hey there. I am starting to take a couple dietary supplements with my meals now. Before then, I never had problems with hiccups. Recently though, I have noticed that several times a day I will randomly hiccup. It's getting annoying. Maybe more frequent too...the only thing I can think of as being the cause is that one of the supplents I take comes in the form of a HUGE pill. It's the lagest pill I've ever seen actually. lol and after I take it I have to eat food otherwise I still feel it in my throat. Could taking a pill this big be the cause? I'm wondering if I have a couple of them caught in my esophogus, but it's been almost a week since i've taking them again on account of my think they are the cause and I'm still getting them. Do you think it's the pills or could there be something else making me hiccup like this?
