Not Aspartame But Sucralose

Huh.  Well it appears the source of my problem is not aspartame but sucralose.  Nestea low calorie drink mix is made with sucralose which can be equally toxic.   It seems the heart palpitations, chest muscle pain and anxiety was caused by this artificial sweetner.  Anyway, I've cut it out of my diet and am drinking just plain water now.  Yuck.
