Canagliflozin
"I am using this off-label as a Type 1 (I've been a type 1 diabetic for 31 years), after I started becoming more resistant to insulin doses, probably due to also being forced to use steroids for the rest of my life.  No problems so far, have seen that my blood sugars do not go sky high from my liver dumping glucose into my system in the middle of the night.  I have not had test results yet, but I have seen a much steadier blood sugar level instead of constant swings from 30 to 500 every day like I had before.  Staying steady around 150 most the time now, so huge improvement."
