My bladder holds 2 fluid ounces

But how do you know this Jacqui, you might ask.  Well the obvious answer is that I've been peeing in to a calibrated plastic 'hat' for the last 13 hours.  Obvious right?  The deal is that between my kidney stones and the fact that I've been passing a lot of protein for the last couple of months, my doctors have decided to punish me with their own version of water torture.  In this case it's pee torture.  I must place a plastic 'hat' under  the toilet seat every time I pee and then carefully, and this is important, CAREFULLY transfer the contents to a pretty orange jug.  If I spill I have to start ALL OVER AGAIN.  I can't really tell you how vile this whole thing is.  Asking a 37 week pregnant woman to collect her pee every time she goes, which is approximately once every hour, and then transfer it to a stinky orange container is cruel.  I can hardly wait until I'm doing it in the middle of the night.  The good news is that it'll all be over at 8:00 am tomorrow morning and then I can whisk the container of disgusting pee, laboriously accumulated in 2 ounce increments, to the lab for a quantitative protein analysis.  The thought that makes this all tolerable is this, thank goodness I'm not the person measuring other peoples' stinky pee in a lab all day.
