Hi,
I switched from Humalog to Novolog in my pump a coupla years ago
and am *delighted* with the results.
Novolog seems to be more predictable
and is more stable for the 3-4 days it's in my pump.
Can you work with your doctor to try a different pen?
The novolog pen holds 300 units, right? I tried a Novolog Jr pen a while back (thinking I might like it instead of syringes for my low-tech backup) which holds fewer units and allows 1/2 unit increments.
