Hi. Am having problems with my morning BS. Am on lantas for night time, and nova rapid during the day. My BS in the morning could be 5.0 and I take 2 slices of toast at 35 carbs. But I find that my sugars rise high, I take double the dose of insulin to try and make sure it doesn't happen. But sometimes I find after 4 hours my sugars start dropping. Any advise please
