| Incidentally, why are you drinking a protein shake every day? I didn't see any mention that you do weights and unless you're bodybuilding there's no point whatsoever in taking on extra protein. All it's going to do is end up adding to your weight.
Once again, you simply need to take more insulin overall. Your daily insulin requirements have changed - this happens all the time and as I've mentioned before, you're another person who's suddenly found their insulin requirements have changed dramatically just as Spring appears to be beginning. Your insulin requirements will not stay static throughout your life or even throughout your week. |
