It doesn't bother my stomach. I don't know why it makes yours hurt.

I used to LOVE coffee. Now I only drink it when I can't poo. It works great in that department, but it also upsets my stomach. Makes it hurt and nauseousness. sad. But I can still drink my tea, so now I drink tea in place of the coffee. I thought maybe it was the caffeine in the coffee upsetting my pouch. But the caffeine in the tea does not do that.
I do pretty good with skim milk and I don't like soy so far. I haven't tried the vanilla soy....ppl say it's pretty good. The International Delight creamers....are they the sugar free refrigerated ones? I've tried the sugar free other brand and come to think about it, I think my stomach hurts on those too! But cheese is ok....so weird lol.
