Aspartame is harmless to most people but bad news for a minority, and if you've got IBS there's a fair chance you'll be in that minority.

If you know an old person with urinary incontinence, try taking it out of their diet. Watch the results after a few days.

Unfortunately the makers of aspartame have some really helpful allies - the people who make the most noise in opposition to it. Utter raving loonies. The highest profile is Betty Martini. "Fit to be tied" doesn't come near it for her.

Makes me ratty and gives me headaches. No big deal but I don't want that.
