I am on glic but not steroids. There was a time when I was on max dose (4x80mg) plus max dose Metformin, plus Actos, and my sugars were stratospheric to the point where my bgl meter greeted me with a HI almost every day. I changed my diet to Low Carb, and the rest is history (But I am not yet history!!!) I have reduced almost everything (meds, weight, waist size) and am currently on minimum dose of Glic and no Metformin or Actos. My HbA1c last month was 46. So the diet and the Glic are working well for me, But when I was in hospital for another matter they put me on an insulin pump, which did nothing for me, thus proving that I was severely insulin resistant.
So the diet was necesssary for me to reduce the IR to the point where the Glic became effective, It was obviously working before but without result seven years ago, but now my one 40 mg tab a day drops my BGL by up to 4 mmol/l which covers most of my meals. I do not hypo any more, but I did while I was reducing my other meds. I still drive, and DVLA has just renewed my licence.
Using the Glic enables me to eat a low(ish) carb diet without needing to be too restricted. For example, last night I had a jumbo battered cod from the chippy, and my bgl only went up by 1.5 mmol/l and dropped back quite nicely to baseline at the 4 hr reading. So I know for certain that I am producing my own insulin, and that I am able to use it when needed. I am still diabetic, which allows me to claim exemption from prescription charges ( mind you, I am at an age when that happens anyway) BUT it also means that my GP will be able to supply me with test strips while I am a driver using Glic.
