Since the active life of even Humalog insulin is 4 hours, then even when
it's infusing only 0.1 every hour, you're getting an even basal -- that's
also why they tell you to change your basal rate 2 hours ahead of when you
typically start to see a rise of BG, such as in the dawn effect.

Before the advent of modern tubing, if you had a low basal rate, the insulin
might crystallize in the tubing, but that doesn't seem to happen any more --
most of what people think might be crystallization is actually a
de-lamination of the 2 layers that make up the tubing.

There are any number of people here that use low basal rates for at least
part of the day, and/or low daily totals, and so far as anyone has said, it
doesn't seem to be a problem.

Natalie, who goes anywhere from 15u to 30u a day depending on how piggy
she's feeling!
