Using R-Novolin to cover protein intake?

Greetings! As the title states, I am looking at using r-novolin to cover protein, as some of my post prandial spikes are starting to get out of hand and cause me to wake up during the night without any success of going back to sleep. Can any of you guys give me your experiences with the insulin along with adhering to a low carb diet. I am well aware about the downsides of using that type of insulin. But at this point, I need something to work. I currently use Tresiba and Novolog. Thanks!
