I do absolutely nothing with aspartame in it. I keep after my husband because he likes a certain breath mint that has aspartame in it. That nasty after taste you get when the first time you drink a diet soda is the aspartame. I got horrible headaches when I ate those breath mints. I couldn't stand the diet sodas. The aspartame can also cause ulcers. DH quit the breath mints and no longer has stomach irritations. They also need to get rid of those sweeteners that are place on tables in restaurants. If you want your tea sweetened ask for some honey or berries with a tiny bit of sugar. I've read the article and that is how my aunt was diagnosed a few years ago. Took the aspartame away and she's a totally different person at turning 90 years old this past June. She can't believe how good she feels.
