I've been adhering to Dr. Bernstein's guidelines for over 3.5 years. Not a real answer to your question since I'm on MDI, but I use R &/or Apridra for bolus depending on the meal. I actually like R because of its longer duration for protein/fat. It's smooth & level. Also helpful for my situation because of gstroparesis. The downside is correcting highs. You could get around that by injecting Humalog, if needed. I imagine it would be tricky at first figuring out basal with R since it stays around for a while & takes about 45 minutes or so to kick in.
