Hi,
Good news on the testing regime.
Though not T2. i do as a T1 use & have many year experience with Lantus (along with a fast acting insulin for meals.)
Getting the foundation right with a basal dose, rotating injection sites regularly is key to fasting BG management, before focus on how diet is affecting you too?
I have to ask this. is your lantus kept stored in the fridge till used?
May i ask with Lantus. Have to noticed your BGs worse on successive days when you are halfway to 2/3rds used of a pen cartridge?
Do your improve the following day after starting a new pen or cartridge?
