Gemini,
I really wish I could help you with this, but it sounds like a question you may need to ask your Dr.
There are other things that can also raise your BSL, such as stress or sickness, among other things.

My DP has type 1 diabetes, and we are having problems controlling it atm... his BSL's are commonly over 13!!! :shock:
So in my view 7.8 doesnt sound too bad... just slightly higher than the recommended...

sorry, I really wish I could help more with advice... I still think running your question by your caregiver might be a good idea, just for some peace of mind.
