Hi Angela,
Even though you reduced the dose, you still want to check the +2 - +3 time frame. Because Lantus is a depot type insulin, you can still see the effects of the .5u dose even after you've reduced. Because the depot (sometimes called the "shed" here) can still influence the numbers for several cycles. In other words, the effects of a dose change, either up or down, aren't always instantaneous.
The 109 is a beautiful number. They just keep getting better :smile:
A low number this cycle isn't a "given", just something to be checking.
