I'm new and am in "information overload" trying to read all the posts. The only thing I take is Elavil which works for pain, but fatigue and Fibro fog are my main problems. I thought I would try one thing at a time starting out the new year. I picked artifical sweetners first because I do use a lot of Equal (aspartane)and drink several Diet Cokes a day. It will be hard, but I've got to try. Would like to hear from others who have done this. How long does it usally take to tell if it is making a difference? I'm a little overweight and am afraid of gaining.
