Okay so I need one because I have unpredictable sudden urges to go to the toilet and I've had every other test going.
So I am booking in with the nurse and we have to keep tweaking the time and date as I am self employed and it's a two day thing what with the not eating and the picolax stuff.
And then I get massively upset at the whole giving myself explosive bowel motions thing. Obviously you get emotional about going to the toilet a lot - but to drink something that will make me do this...
So the big question is is it painless - the emptying your bowels bit - I don't care about the procedure you get drugs for that.
