When to test?

140 is too elevated.  It doesn't matter if it's 60, 90 or 120 minutes after you start the meal.  A non-diabetic will not test out that high after a breakfast like that.  Onions, peppers and tomatoes (especially) have carbs and if you're eating too much of them, your blood sugar will rise.  Try cutting down on the amount of them when you make your omelet.  Most everyone's blood sugar will rise after eating and then fall back to normal.  A non-diabetic's will not rise as high and will go back to normal faster than mine, for example.  How high mine will rise after a meal depends on the amount of carbs in the meal (which come mostly from the vegetables) and how much food I eat.  I keep bell peppers and onions in zip lock bags and just slice off what I want to use.  They keep almost a whole week that way.  Check the carb content of the Kefir.  The containers I looked at were pretty high in carbs so I don't drink it.  Although the ADA has changed its recommendations for the food pyramid, it's still very much based on grain and if I were to eat as they suggest, my blood sugar would remain elevated and I would be on meds.

I don't know.  Sometimes I've tested just a minute later from the same bead of blood and gotten two different readings, too.  I think these meters are good but they're not 100% accurate.  I have 4 meters.  One is about 4 years old and takes 15 seconds.  The other 3 take 5 seconds, and they're all Bayer Contour Ascencia.  The oldest one will always register around 20 to 30 points higher than the other three.  The other three are normally within 10 points of one another but then I'll get different results from the same meter from the same bead of blood.  It's annoying because I feel like nothing is exact.
