@JAT1 obviously you are on a routine for insulin devised between yourself and your health professional and that is for you to decide. However, you are fearful of taking too much insulin and want to have lower carbs. By taking a fixed amount at each meal you are then having to eat that amount of carbs. Which to me seems the wrong way round. If I’m not hungry later in the day I take no insulin and eat no carbs. Other days I eat a lot more and therefore take more insulin. It results in a more relaxed life. Maybe discuss carb counting with your health professional.
