What kind of sweetener have you been using?
If you've been using Splenda, then yes I have heard of people complaining of stomach problems/bloating/cramps when using it, especially that much in a day.
If it's Aspartame or something else, then I'm not sure. I know some people don't react well to it, I'm just not familiar with the symptoms.
