CR741,
I wouldn't imagine its anything to worry about but if it's causing you concern do see your gp. When I was a child I often had hiccups and my mother would tell me to slow down when eating, it was good advice and it stopped once I listened to her advice, but as your hiccups are before eating we can safely rule this out.
Try searching the net for suggestions and tips on how best to deal with hiccups, you may be surprised at what is suggested! :wink:
