LOL! I get the hiccups much more often than usual when I'm on the MC. Never for two hours though! have you tried the old remedy of taking 13 consecutive swallows of water and then coughing? That ALWAYS works for me to "cure" hiccups!

Supposedly hiccups are air stuck in the diagraphm and little muscle contractions trying to force the air *bubble* out. I found forcing myself to burp after every hiccup stops them pretty quick. Pressing on your diagphram area while burping helps too. now I gotta do is learn to spell it. LOL!
