Like "Yep, pcyoung38 is right. My doc told me a little differently, to aim for 80-120. So anything above, say....150...is what I would count as "high" and needing a correction. Usually when my liver dumps, though, I get a lot higher readings, like 300 range. That's how I know that it wasn't simply something I ate the night before that usually only cause a moderate high."
