Hello Everybody, I've been reading these boards for quite some time, but never had a reason to post before. I'm a student nurse with quite a bit of CNA experience, but not much nursing clinical, yet. I'm hoping someone can help with a question. I'm trying to lose weight, so I've switched to diet sodas instead of my regular high-octane ones. My DW heard "somewhere" that aspartame can cause or aggravate headaches, which I get rather frequently. The web search I did has a lot of conflicting information on both sides of the question. Does anyone have any personal experience, or knowledege of a definite scientific study? Thanks in advance. Harold
