Yes. I had the same symptoms. In addition, I had a number of other medical problems as a result of taking sucralose (Splenda).

I like to say sucralose, not Splenda, because that is what Splenda is. And it is in a lot of stuff. The package doesn't have to say Splenda to have sucralose in it. You have to read labels.

Every morning at work, I would make myself a cup of coffee. I mixed two packets of Splenda? in my coffee. In addition, I used Coffeemate sugar free French Vanilla liquid creamer, which also contains sucralose. I would drink two to four cups of coffee a day.

My anxiety was extreme and I could not stand it anymore. The best way to describe the way I felt after drinking one cup of coffee with sucralose in it was that it was like drinking six cups of coffee. My heart was pounding and my anxiety was soaring.

I decided to stop using caffeine and start drinking decaffeinated coffee hoping that this will help. Therefore, one Monday morning, I started drinking decaffeinated coffee. I made it the same way I did with the caffeinated coffee, two packets of Splenda and Coffeemate creamer. After drinking it, I felt exactly the same way. I complained to the person in my office, who is responsible for ordering the coffee, that, the decaffeinated coffee she purchased was not decaffeinated but was really coffee that had caffeine in it.

I continued to drink the decaffeinated, without any reduced nervousness.
