Hi Anna,
Re getting brilliant control during trial period, I really wouldn’t worry too much about that as I wasn’t expected to get perfect sugars and indeed it’s quite rare during this period and even told that HBA1c could rise a little. It’s just getting used to the pump and all that entails. Re those hormonal swings, at some stage you’ll be able to use temp basal which will get faster reaction than amending Lantus a day or two later. I admit that I still have to get to grip with this though some nine months from starting.
One problem I found was worrying that a high sugar was as a result of a bad pod rather than a bad me and being unable to see the window with the cannula as it gets steamed up. The new pod will have a light blue cannula so should be easier and with luck maybe you’ll get the smaller pod by the time you officially start although we’ve been promised that it’s around the corner for a year now !
