Most type 1s on a basal bolus regime (who's is what your insulatard/actrapid is) will adjust their bolus (fast acting/meal time) insulin according to what they are eating by carb counting. Calories don't have anything to do with blood sugar, the thing that impacts on blood sugar is how much carbs you are eating - all carbohydrates eaten will turn into glucose and raise blood sugar. Carb counting adjusts you bolus dose by working out your insulin:carb ratio (ie how many carbs can 1 unit of insulin deal with), once you know your I:C ratio you work our your insulin dose for a meal based upon how many carbs you are eating, if 1 unit covers 17g of carbs you divide the total carbs in what you are going to eat by 17 to work out how many units to take.
Where are you based
@SHmano ? A lack of hypo awareness nd overnight hypos would certainly meet NHS funding criteria for a pump.
There is a free NHS course on carb counting available online -
