I believe the OP has said she's diet controlled on another thread.
@Jogreen21 I don't know if you feel able to write down a day's food and test results so you can get more specific suggestions. If you don't want to do this, then that's perfectly ok
I recommend something like MyFitnessPal so you can get an idea of how many carbs, etc, you're eating in a day. That way you could see if there are any obvious areas where you may need to make adjustments.
I would also have a chat to your diabetes nurse and see what they suggest. If you're eating moderately and still getting high numbers, then it would be good to have a chat to them.
You may not be able to do this, but if you can, I also recommend having a routine and having similar things for your meals and at similar times. I know that might be hard with an eating disorder so please get support and help and don't rush that. But, in general, spreading your carbs through thevday rather than having all of them at one time can help, for example.
I also suggest testing 90 mins to 2 hrs after eating. You will then see the affect certain meals have on your blood sugar.
