I test at least 8 times per day--more if my BG is higher. Amount I test has not really changed. It is the warning I love and hate, especially overnight. When I hit a rough patch, I feel like I get alerted a lot at night and do not sleep well. Been a roll, lately though. Good nights sleep!
With my new MM Revel CGM I still test before & after meals and before bedtime. With the CGM I find the rate of change and low BG warnings to be most useful. With hypoglycemia unawareness I'd often be <50 mg/dl before I ever had symptoms which made recovery and severity more challenging. Now I get a heads-up which makes getting my BG where I want it more easy. Another thing I like is that with all the data it collects I can more easily spot high/low trends and adjust my basals and bolus rates more intelligently. Many will complain about the varied accuracy of the data, however I pay attention to the trends and not the individual specifics of each measurement. It isn't perfect by any means, but it is a useful tool that has helped me to lower my A1C and to avoid catastrophic hypoglycemia.
