Unfortunately this is likely to affect your blood glucose overnight (next 12 hrs ish). I'd recommend setting an alarm every couple of hours and testing to see what your blood glucose is doing. It's probably going to go low, and keep going low. You might want to gather your hypo treatments, so you know they are to hand and within easy reach.
This is really an individual thing, different for different people. If you are sensitive to dose changes your blood glucose could plummet, which is really scary. OTOH, it's possible the dose change will make only a small difference. It's also possible your liver will get in on the act, perform a dump and send your blood glucose sky high.
I'm sorry to be of such little help, but truthfully, no one knows what effect the double dose will have. You need to keep monitoring your blood glucose for safety.
