Congrats! I will have to read your other thread to get all the details.
I will always have a sweet tooth, so one way or another I always will need to taste something sweet. I hold out the hope that one day the perfect artificial sweetener will be developed. Unfortunately, despite claims by Sucralose/Splenda/Stevia , the best one out there is still Nutrasweet. However all of the above are better than Saccharin (yuck).
Of course the safety of every artificial sweetener is thoroughly attacked before being accepted as self-evident. If you hear someone criticizing the safety of one, just make sure she or he isn't of the same ilk as those who only eat birdseed and drink chlorophyll and do fasting to the point of near death. Be a good scientist in such matters, not a hippie full of superstitions.
But I am digressing. Congrats again on your (hopefully permanent) success!
