I found starting a pump a bit like starting MDI for the first time – I had to learn a lot of new things; like using temporary basals – I found that a 50% lowering of basal levels for two hours worked really well for hard exercise (as always I needed to find this out through trial and error) and that pasta is best server with a dual wave bolus. But saying that I didn’t have to learn all the basic diabetes stuff again, so it took me about 2 months to get really good on the pump.
Hard work at first but definitely worth it!
