I have exactly the same issue. Over and over again, I get the instructions end. It's uncanny.

With one box recently, I actually sat and memorised which way round I had to be holding the box to achieve pill-access. With another lot, I gave up, moved the paper to the other end, and continued. But Kent's right - I suppose just getting rid of the paper would be a sensible thing, as long as you feel you're familiar enough with the information contained within.
