You may begin to develop insulin resistance if using large/frequent doses (type II diabetes mellitus), but all you have to do is take a break from it and you'll return to normal.
Besides, steroids increase insulin sensitivity, so that will help to cancel out the aforementioned effect.
I will warn that if you're already pre-diabetic, it would be best to use just enough slin to keep BGL low and not need a bunch of extra carbs, which could push your insulin resistance over the edge. But you probably don't need to worry about that unless you're middle aged and/or in exceptionally poor health.
