Do you know if there's any stronger than novorapid
Stronger is a tricky word: Do you mean dose for dose, or more effective at a given time.? Some things to consider, always in discussion with your dsn and/or doctor:
1) If you have not already, perhaps google 'pictures of insulin profiles Fiasp vs Novorapid' to see a comparison of blood sugar lowering effect vs time.
2) The other 'side' of the equation is looking at what your meals consist of: looking perhaps at low carb diets on this site and also looking at 'mendosa.com' and on that site, Glycemic values: this gives the GI and GL of commonly consumed foods. (definitions included). Certain foods will tend to cause earlier BSL rises than others, modifying the foods consumed have helped people moderate the height and timing of their BSL rises
3) On this site, some TIDs have discussed delaying their food intake for say, 1/2 hour or 1 hours after taking insulin like Novorapid to better 'match-up' insulin's blood sugar-lowering effect with the blood sugar rise from the meal.
Please stay cool and flexible.
