I know what you mean about being excited about a sore throat! I've wished countless times that the malaise would just turn into the flu. It rarely does. Since getting the IUD out, I am very rarely sick, even when my family is. I guess that's a good sign. Something's working right with my immune system.
I researched the Aspartame thing early in my recovery and stopped using it then. I agree it's a good idea. I even stopped using Splenda (sucralose). I only use real Sugar or stevia or xylitol.
