Hey.... I know it makes me thirsty. I just had one of those packaged ice cream cones and i drank a whole glass of water with it. Nobody else i know gets thirsty when they eat ice cream so how many of you get thirsty when you eat ice cream??
I'm among those who don't get thirsty (although I do get a little "borderline nauseous" from it - must be a dairy thing, I guess). Not to be a big downer, or not to assume the thirst thing isn't just some little "quirk type of thing", but if you do a search for "thirst after eating ice cream" you'll see lots of reasons it makes some people thirsty. The one I'd be most concerned about might be elevated blood sugar in a person who has Type II diabetes and may not know it.
