I have such a terrible headache today. I rarely get them like this.....sometimes a little stress headache but medications are not touching this and I already take Ultram for my back. I was thinking, my mom gave us some oatmeal she didn't want...one kind were these little packs saying only 100 calories or something...I just figured they were little. So I made one and ate it, it tasted funny, an after taste so I checked and it had non sugar sweetner.... I never drink diet anything anymore because I had tons of headaches and someone told me to stop to see and sure enough very few headaches. I am hoping this is what happened. I sure dont want to be getting sick. I rarely get sick. Do you guys get headaches from artificial or non sugar sweeteners?
