It is really more dependent on the RATE and DIRECTION of the bg
change, not the absolute value. I'm attempting to draw an inference
from the level and what I expect it to be later based on unused
insulin. If she's low and going lower, going to sleep will usually
stop or reverse the trend. Conversely, if she is too high and
trending up because of a bad dinner bolus, pizza, whatever.... more
insulin will be required. As you have surmised, it is difficult to
predict. The bed time basal just helps things going in the right
direction. With a PERFECT bedtime bg, things will still be different
at 2:30 on different days. I only attempt to keep Lily from crashing
or being very high at 2:30. After that check, all has been smooth
sailing for years now. The only reasonably guaranteed stable early
sleep period occurs on days with not extra activity, a very early
dinner and no food/insulin for 5+ hours before bedtime. This set of
conditions is rare to non-existent in our household but it does occur
and usually her bg's are very predictable under that scenario.
