Some of us are genetically unable to process saccharin, aspartame and other artificial sweeteners. If I have any of those, I can taste it for hours and hours afterwards as it circulates and recirculates within the body. I assume it gradually gets excreted by my kidneys. At high dosages there is some nausea. I once bought a bottle of soft drink that had no indicators like 'Diet' or 'Sugar Free' on the label. I drank all of it, about 700 mL. An hour or so later, I had the distinctive 'sweetener taste' in my mouth along with some nausea. Because I avoid artificial sweeteners like the plague, I was temporarily puzzled by this. I thought back over my day, and worked out that I had had that bottle of soft drink. I dug the bottle out of the bin and examined the label for the ingredients list. There I discovered that most of the sugar in the soft drink had been silently replaced by artificial sweetener, most likely as a cost reduction.
