Like "It sounds like you might only be taking one shot of long-acting insulin to supplement your body's "basal" insulin needs and no short-acting meal-time or "bolus" insulin? Because you don't appear to have a very set meal schedule, it might be enlightening to see what your BG's are 2 hours after you do eat. Some people report that coffee appears to cause their BG's to rise so it might also be informative to find out what your BG might be around the time of your 2nd coffee in the morning. Diabetes is a very individual disease. The more information you can provide, the more data you and your doctor will have about what is actually affecting your blood sugars. Even better the data would include a food log with the carbohydrate gram totals of the food you've eaten along with the BG's."
