Usually at 10pm at night I go to bed and my blood sugar is normal at a good range of around 6.5 I do my last bit of insulin at 10pm which is lantus slow acting and I do 8 units the last bit of fast acting I do is at around 4:30pm. I can guarantee at around 11:30pm I get a low of around 3.0. I treat the low with a 1/4 cup of lucozade and a biscuit as recommended by my diabetes team. My sugars always go back up to within norml range but then once morning comes round again my blood sugars have dropped once again to around the 2.5 mark. I'm so confused as to what I am doing wrong to cause this as it has only been happening in the past couple of days and I haven't changed any of my insulin doses. I will be contacting my diabetes team to ask them what to do but in the mean time was wondering if any of you guys could advise me on what I'm doing wrong.
