I've been amazed lately how small changes have produced big results in my control.
About six weeks ago, a major change in my personal life caused me to change my eating habits quite a bit. I used to eat large dinners all the time, and I found that my blood sugars were often high in the evening and the following morning. All of that is changing now, though.
For one thing, I'm eating out less, and eating much smaller dinners. My bedtime and morning blood sugars have been much more likely to be in my target range, and I'm sure it's not a coincidence. I've had to reduce my Lantus dose as well, by a couple of units overall (one unit each in the morning and the evening -- I split my dose and take half with breakfast and the other half with dinner, in order to smooth over the peaks and valleys of coverage).
The other change is that I am a little more active, especially with the improvements in the weather. It was a very cold winter for Colorado, and so I didn't ride my horses as much during the cold months. On top of that I was sick a lot this winter. As a result I've been riding more lately, and I hope to increase that even more in the next week or two.
It's amazing how much of an impact small but substantial changes like that can have on your blood sugars!
