When my blood sugar falls or rises very quickly, my G4 sometimes stops working for at least two and usually four or five hours and displays the ??? or a timer symbol. Does this happen to anyone else?
The chart below is typical of what happens (If I do any exercise at all my BM falls very rapidly irrespective of how I set my pump or what glucose I consume - When I stop the exercise my BM rises just as rapidly and can be difficult to control).
