    I know this doesn’t really address the possible causes but have you changed your exercise routine? I know when I’ve been high the last thing I want to do is take exercise and yet if I take my dog for a walk it can lower my blood sugar level quite quickly. Just a thought.

    @Kimberley2026 Hi, one thing I picked up on was "I feel I am taking bucket loads of insulin". I remember when I moved from Lantus to Levemir I couldn't believe how much more basal insulin I needed. I kept doing basal tests & increasing the Levemir until it suddenly just "worked". I thought I was taking a lot of Lantus (about 60 units) but the total of my split Levemir was nearer 90. The split was odd too 30 in the morning, 60 in the evening, but I was getting the best results I'd ever had.
    Basal testing is a pain in the neck but it is vital.

    Kimberly, I had the same problem for over a year and like you I could not imagine what I was doing wrong. I said to my doctor its as if the insulin is not going in, he changed my needle to a 5mm instead of 4mm and hey presto. The moral of the story is medically speaking size does matter.

    You could have developed insulin resistance. Worth going back to your diabetic clinic for a chat. Are drinking sufficient water? Dehydration can cause elevated blood sugars. All the best

    Not sure why Metformin as well as insulin? In my case Metformin caused Raynaud's Syndrome [Extremly cold hands & feet] after which I stopped Metformin, started insulin & have never looked back. The point is to adjust the number of units of insulin & then no need for Metformin. I have always had high [over 7] fasting levels which I put down to my liver dumping glucose. I use Novorapid to bring this down before breakfast & so limit the peaks after because of starting at a lower level & having breakfast at a time when the Novorapid has started to work. I am not sure how many units of Novorapid you are taking but this should vary depending what & how much you are eating; also depending how much or little exercise over the last two or three days. I tried the Libre sensor & found it inaccurate, in my case tending to under read & on occasion showing below 4 & so a hypo, when by finger pricking I was in fact not. I would suggest changing the number of units in particular of Novorapid to see if a better result can be achieved. I also use Levemir but a few units more or less doesn't seem to make a noticable difference. The focus should be on changing the number of units of Novorapid.
