Welcome to the Forum!
Congrats on getting your A1c down!
Are you doing the sliding scale or a bolus injection for the carbs after meals? It would appear to be the later, since you made reference to the (B - 1:12, L & D 1:10). I am assuming that your breakfast ICR is 12 and your lunch and dinner ICR is 10. Did your Endocrinologist happen to supply you with your ISF as well? Are you using a pump or MDI's? Do you have an exercise routine, before or after any of the meals?
I'm sorry for all the questions, but these are some things that we will need to know. I am not really familiar with Apidra, other than knowing that it is a fast acting insulin. It appears that if you are calculating your bolus injections, (based on your ICR, ISF, blood glucose readings and carbs consumed), that you may need to increase one or the other insulin's, but this is also dependent on your exercise routine and activities before and after your meals. I personally find it odd that you are taking a long lasting insulin (Lantus) injection at dinner and not after dinner or before bedtime. However, this would depend on your fasting level or out of bed blood glucose readings. If you are holding them from 70 mg/dl to 99 mg/dl then you are doing great and it is working for you.
