I go 3 days without going very frequently (and if I go a lot one day or it's very soft, I may go 5 days without going). Also, once when I was a little girl I didn't go for TWO WEEKS!! My mom gave me x-lax and it STILL didn't make me go! That was "back in the day" (1960's) when people weren't so obsessed with their health. I kept drinking prune juice and sitting on the toiled and FINALLY went.
There is no normal. That article is wrong, EVERYONE doesn't go daily! Some do, some go every other day, every third day, THREE times a day even.
