Can someone please check my maths for me?
My insulin pens hold 300u.
I take 80u per night.
So, each pen lasts 3.75 nights.
I'm gone for 6 weeks, which is 42 nights.
That means I need to take 12 pens.
Is that right?

@aby The exact answer would be 11.2 pens, but since you can't really have 0.2 of a pen you would indeed round up to 12.
If you were to round down the time each pen lasts to 3, then you'd need 14 pens, so I guess it depends on whether you're concerned about needing the extras.
