Massive eating troubles

ok heres the deal. i cannot fit these calories in. its not my appetite. its that there arent enough hours in the day. i need almost 5000 cals and am trying for 30/40/30. is it ok to have carbs at just over 100gms per high carb meal and fats at about 45gms per meal? my morning blood sugar was 3.6 (canadian) so my doc says i have good insulin sensitivity. thanks
