You are doing a good job keeping your BGs in a relatively tight range. In other words, the width of your 14-day trace is not too fat.
You have a strong pattern of lows, 2x/day, followed by highs. Solve the lows and you’ll find the highs will tend to fall back in range, too. If this were my report I would start with going after the hypos. I think your overnight hypos are leading to morning and afternoon rebound highs.
You will need to think about why these lows are happening. The easy answer is that you have too much insulin or not enough food or exercise that drives the BGs lower. I think you are very close to producing a much less variable BG with a a high percentage of your time in range.
Is it your habit to take high BG corrections in the evening hours leading up to bedtime? If that’s the case then you should look at your dinner dosing amount and timing. If you are correcting the highs with insulin, you might consider giving less insulin to correct.
Since this is a strong pattern, I would not hesitate to set an alarm for 1:30 a.m. to check your BG and treat if necessary. Make an extra effort not to over-treat a low if you have one. The 15/15 rule (eat 15 grams of carbs and wait 15 minutes to check again) does not work well for most people. I will often correct a low BG by taking 1 glucose tab, 4 grams of carbs. If I have a unit or two of insulin on board (IOB) then I may take a second glucose tab.
If you are not taking insulin corrections in the evening hours before bed, then you need to consider your basal profile. You may need to back off on the basal rate starting at 11:30 p.m. at least through 5:00 a.m. The key here is making the basal rate change two hours before you wish to see an effect.
Your late afternoon, around 4:30 p.m., lows are a classic time when a lot of us tend to go hypo. I would reduce your basal rate starting at 2:30 p.m. I like to make my basal rate changes in 0.1 unit steps but this amount needs to be adjusted based on your usual basal rate. My rates vary from 0.4 to 1.2 units per hours, so a 0.1 unit change is a reasonable step. If your rates were much less, like 0.1 to 0.5 units per hour, you may consider basal step changes of 0.05/hour.
Good luck. I think you’re doing a better job than you might give yourself credit for and you’re not that far away from much better performance.
