I think it's more common now to call a bidet insert a bidet. So just an inser that you fasten between the seat and bowl with an arm for turning on and off the spray. That connects to a T adapter at the inlet on the toilet. Works really good and costs 20-80€/$

I read some study that aspartame changed the gut flora. Sugar probably does the same thing though. But sometimes there's interactions that science forget to study
