Has anyone heard of Splenda causing hallucinations? My 86 yr. old mother called to me to look for a tiny crocodile that went under a chair. I thought it might be a lizard -although I've never seen on indoors here - so I looked armed with a broom and a pan to capture and contain it. Couldn't find it and the dogs and cats did not seen to be concerned when they walked by the chair- so just thought it was gone. THEN she called to me again and wanted to see aobut a man in the dining room! there was none so then she said Must be seeing things. I thought YEP! The only change has been starting to use Splenda in her iced tea for the past 2 weeks (1/3 cup to 2 Qt.) No new meds or vitamins either. Thanks for any reply.
