i have had good blood readings for 3 days now which is very good for me in the range of 5 to 8. Apart from my last reading before bed. It has been around the 14 mark. I have done my injection to the correct carbs that I have eaten. I inject 12 lantus at night usually around 9 to 9.30pm. I have woken up and tested around 12.30am and it's still the same. My morning reading the day after can be down to between 7.0 to 5.0. Any advice.
