What time of day/meal are you testing after?
The reason I ask is when I was first diagnosed, I went nuts on the testing. I took readings before/after every meal for about a month and entered all the data into the software program that came with my meter. What this showed me was that in my case, my BGL's were steadily highest in the morning and sloped off to almost normal towards night. Knowing this, I modified my eating habits accordingly and now only randomly test to make sure I'm on the right track.
