I think Geranium plants are also toxic to household critters, but I can't remember if that's for cats or dogs or both or all of them, including human children critters.

In the case of my unhappy GI tract that means ejection.
Artificial sweeteners often make me pee like mad, but I'm not sure which specific ones --unless it's all of them. Trouble is, they're in toothpastes, too, and I soon learned to not use toothpaste in the AM before the usual traffic jams during the commutes to Denver on I-70. ("Ohhhh, man, c'mon, next exit. C'mon, c'mon, c'mon!")
I found using just bicarbonate of soda as a dentifrice worked pretty good for the AM ablutions. Must watch the sodium intake with that, though.
