@SarahSon - That is interesting about drinking the water to get rid of hiccups. I have always wondered what actually causes hiccups. I always feel so bad when babies get them and you don't know how to help them.
What has worked for me in the past is trying to hold my breath for as long as I can. I take a deep breath and hold it for as long as possible. It does not work every time, but seems to most of the time if I can hold my breath long enough.
