Hi tame, sorry I'm late in my reply; haven't been online much this week. I see you've gotten some good advice on this thread. Personally, I agree with "all things in moderation."
We can buy Diet-Rite cola in our area and I do drink it at times. I like the flavor of Splenda better than the other artificial sweeteners. I do, however, try to limit my intake of artificial sweeteners. LOL, nothing takes the place of "real" Coke.
I have a friend who had serious health problems (symptoms similar to MS) that seemed to improve quite markedly once she gave up aspartame. For starters, it would probably be wise to start with reducing how much you use of that.
My problem is I know what I "should" do for optimum health, but I don't always do it.
Good luck in your quest for good health!
