Well, normally I'm on top of managing my D, but the time change this past weekend slipped my mind. Not, really, I did change every clock in the house, watches, and clocks in the car. But forgot to change my pump and meter until Today (Tuesday Morning). Sunday's BGs were all over the place and now I know why.
If you forgot, take the time to do it now. If my post reminds one person, I think that is worth it.
