I've noticed recently then when I sit down to have a nice plate of warm turkey bacon, I get a strong hiccup on my first couple of swallows. This usually stops happening as I continue eating.
Hiccups are not a normal thing for me, since I have excellent diaphragm and breathing control from years of playing wind instruments. The only other time this has happened, was when I would take the first drink from a cold glass of coke or soft drink. But I don't drink soda anymore, so it caught me by surprise.
I have the same problem. I get one strong hiccup as soon as I swallow cold soda. sometimes food makes it happen too. Well, at least im glad to know that I'm not alone. I stay away from soda now, or drink it extra slow and careful.
