I have had type 1 diabetes for 18 years now and I have had good control all my life (I have just turned 21). Over the past couple of days my blood sugar levels have risen into double figures and not been below 12.0 (my normal is between 4 and 11). Now within the past month I have started to carb count correctly and my dietician has recommended I cut my lantus down to 20 units (originally 28). Now my highs are difficult to combat over the past few days and I don't know why. I use correction doses but it barely touches it. I have increased my lantus up to 25 and it has helped but I am still having to take correction doses even when I haven't eaten. Is this something someone else has gone through or any advice would be welcomed. I haven't had anything like this before and my hbA1c is between 7 and 8. I have good control up until 3 days ago. Also I usually take my lantus roughly around 8pm every day.
