But I'd like to be able to tweak basal a bit more than I can at the moment - the long acting insulin means you're committed for 12+ hours and I'd like to be able to react to what I want to do rather than having to commit at that point. But I'm going to struggle to get that past the DSN...
Will keep trying as I really want you to get this pump as I think only that will give you the flexibility you want!
But for now you need to get the DSN happy using MDI. You need to clarify with them what are they looking for before they will consider you for a pump - Fewer spikes? Fewer hypos? Lower HbA1C - of what to what?
You say you vary your basal already so you probably have something like (made up numbers for illustration, the relative change is the point I am making). (And definitely do a basal test to get the base level right).
Inactive day - 12/12
Normal day (1 hour active in evenings) -12/11
Active day (several hours of activity) - 10/10
Then if on:
A planned Active day a surprise storm comes in - you eat less / inject more bolus / correct with bolus away from meal times, then go back to 12 in evening.
A planned Inactive day you get a surprise call to the mountains - you eat more / inject less bolus, etc, lower basal to 10 in evening.
A planned Normal day becomes an inactive day - increase evening basal to 12
etc
So I don't entirely agree that you are committed once morning basal administered, there is still some flex.
Not perfect - though there is some flex on 2x Levemir injections per day - but that is a downside of MDI... and you're stuck there until the DSN is happy. If you can prove your ability to manage this to meet their targets (of x,y,z?) then hopefully you can get that pump.
