Humalog and Lantus insulin pens

Any other of you type 2s using these? What does it take for you to get good numbers? I'm currently on 2 small, fairly low-carb meals a day, with 4-6 Humalog units per meal, plus 24-26 units of Lantus morning and bedtime. 83 years old and type 2 for 27 yrs. Insulin only for the last 4 yrs. Before that, diet and exercise.
Would like to discuss mealtime Humalog timing, at what BG levels on your CGM, and results. Due to stroke a year ago, can't exercise much anymore to reduce insulin resistance.
