Welcome, I feel if you can keep bgs below 100's without medication that is great. Once I spiked higher on a regular basis I knew I needed medication. I like to keep my bg average as close to 100 as possible.
I like my average to be around 100 which would give me an HbA1c of 5.1. Lately my fastings haven't been cooperating and they are usually in the 100-110 range. But I limit carbs so my 2 hour numbers rarely go over 110 or so. I need to see more fastings in the 80-95 range to accomplish my goal. At some point I may ask doctor for an Rx for Lantus or Levemir to help accomplish this.
