okay first you have to know somethign about me, I am a instrumentation technician and an engineer. I don't think ANY of the CGM technology is all that good but I am comparing it to industrial controls.

The minimed CGM gave me acceptable results, btu I learned a few tricks. #1 trick is calibration. I made sure my sugar was stable for at least 2 hours before I calibrated my sensor. By making sure I was stable, the sensor gve me fairly accurate readings. The sensor is great at tracking overnight trends and it will give you a great idea regarding your overnight basal rates, which for pumpers are the hardest to program,

I waited some time before getting the cgm, I believe for me starting both at the same time would have been too much. Too many odd deays to remember (change the infusion set every 2-3 days, calibrate the sensor every 12 hours, reset the sensor counter every 3 days, charge the sensor battery every 7days) it's a lot to remember. I am afriad it could be overwhelming.

Starting a pump is a little like starting over again. first you take your total long acting insulin dose divide by 24 and that's your starting basal rate in units per hour. Then you program in your carb ratio. a litte at at time, you watch your hourly blood sugar, and progressively skip meals. once your basal is tuned your sugar stays flat even if you skip a meal. it's harder then it sounds. Ofetn you will end up on less insulin you are using now. Then you re-calculate your carb ratios, because if your basal is too high, your I:C is often too low.

I highly recommend buying Pumpin Insulin, by John Walsh and Ruth Roberts. amazon link here. It's a great resource, and it's generic to all pumps.

good luck!!! ask if you have more questions!
