Well, my fiancé was doing a lot of NutraSweet (coffee, Diet Coke, etc.). I printed out some of the posts here and she decided to cut out the NutraSweet for a couple of weeks to see what happened. The results have been quite good.
She has been having headaches for years. There is a noticeable reduction if not elimination of headaches. She has problems with anxiety and panic attacks. She has not experienced one since coming off the NutraSweet.
There are other noticeable effects, too, but suffice it to say, cutting out NutraSweet in her diet was a good move and something she plans to continue.
