| Do you have to take all the levemir at bedtime? Could get better results by splitting ...
The yo-yo effect isn't good either, and since you're working really hard, that increases the effect of the insulin.
I would start by measuring the BG every 3 hours, but get a good nights sleep.
The next step is looking at your diet. My "system" is pretty simple.
My schedule when working out:
0715 - 4 slices of bread, cabbage or carrots
1030 - 2 slices of bread, pieces of apple, pear, orange and pineapple
1330 - 2 slices of bread, pieces of apple, pear, orange and pine apple
1612 - 2 slices of bread, no insulin, going to the gym
1830-1900 - dinner (healthy one)
2030-2130 - bedtime meal, one/two slices, fruit or vegetables.
With this I've lost fat, gained strength at the gym, my latest a1c was 5.3% and the next one I think will be lower. I rarely have BG under 4, and rarely over 10.
With low BG I usually drink one or two small glasses of apple juice (10g carb per 100ml).
I know it's a lot of bread, but have no idea what to replace it with. Working on that though. It's highish fiber bread and considered to be the healthiest.  |
