Not sure if this is an option for you. I'm about to be able to test a continuous BG recording device. It records your BG 24/7 over a week. There is 2 types that I can try, one that has a display and one that "silently" records the measurements and gives you a chart at the end of the week. As we in Sweden get everything for free if you have T1 (insulin, needles, lancets and BG device with test strips) a BG measure device is a test thing only. If you get like a couple of really low BG scores or your A1c is off the chart you get one for free. It could be a good investment also, but for now I'm going to try one out. Maybe you could "hire" one for a week? Just to keep track of the stats during day and night as you say. Someone suggested setting an alarm to check your BG during night, it could work but recent studies shows that the body stresses out due to the alarm and the mmol/l could get several whole points higher between the alarm and you getting your measurement. So, it's not a reliable way to check things during night. Many insulin pumps can be upgraded with this feature. Ask your doctor, it could be worth a try?
