@SueJB that sounds interesting a million and one things I could say to them but No1. is especially if they're aiming to be diabetes consultants, just remind them that their patients are actual people too.
Yesterday was a bit of an up and down day BG wise, nothing too horrendous but certainly not ideal

This morning I was 9.5 so gave my pre-bolus plenty of time to kick in before eating, probably too long as I'm now 3.7 heading south but I've had a left over M&S raspberry jaffa cake which was probably the cause of yesterdays up&downs - they are rather good though!
