@kelp84 one effective way to reduce your hba1c is to focus on the night time BG levels.
You are asleep for on average 33% of the day. You're not eating (hopefully) during that time, so if you can get your blood glucose down to a normal level before bed and keep it there overnight you will significantly improve your hba1c.
do this by A) making sure your overnight basal requirements are met correctly and B) eating no less than four hours before bed, then checking and correcting (either up or down) before you go to sleep. Some people are scared to take fast acting insulin before bed, but if you know your correction ratios you can safely make adjustments.
