I vividly remember the old "disgusting powder downed with 4-5 litres of water in two hours" followed by thebsame time on the toilette. Nowadys, while still not delicious, the stuff is acceptable taste-wise, takes all of 1 litre of liquid and after three trips to the bathroom you're good.

No idea ehy people are so afraid of that. Ifbyou have nothong, fine. If you do, it migjt very well save your live or very serious surgery down the road. After all, whatever it is, it wont go away just because it remains undiagnosed. After all, a falling tree in the woods without anyone next to it still makes the same noise.
