I went a little nuts with the BG testing for a month or two when I first got a meter. I learned a lot about how different foods affect me. Doing postprandial readings after a meal (every 30 minutes for 2 or 3 hours) helped me figure out that I was reactive hypoglycemic. Even some low carb meals could spike and crash my BG - giving me that 'raid the pantry' need to eat. I couldn't figure out how some LC meals left me craving food between meals while others didn't. Testing BG helped me figure that out. I learned how I needed to eat to maintain a normal BG arc after a meal. Satiety between meals is a great thing. So while I did get a little overzealous with the BG testing for a while, it did have some benefit for me. I'm glad I did it. I only spot check a couple of times a week these days, sometimes before a meal and sometimes after. The numbers are staying within reason, so that's all the testing that I need.
