Sorry one last question - I've prepared the Plenvu in 500 ml litres and I'm sat here stirring it for the better part of 15 mintues but it's not at all clear! The bits are all dissolved but it's more of a cloudy colour, like bitter lemon, is that alright? Can't seem to reach the ward to check.
I've had several operations prevoiusly but for some reason this one has me absolutely petrified!
