Hi hippychick, Yes Equal and Nutrasweet are good ones for Fibro flare-ups.
Cafine is another good one also. I am so sorry that you are going through this flare-up right now because you didn't know what was in your food and drink.
I make my own meals and drinks so I know exactly what is in them. My brother brought over a dounut and Pepsi the other day and me not realizing I was craving just the cafine had Pepsi three days in a row. And my flare is going strong due to my own stupidity. Yes I'm off the cafine now and am starting to feel better, but it's really no consilation to stupidity.
Hope you feel better soon.
