Okay, I now know where you are coming from. When I started I had a HbA1c of 11.2 after being put on a diet plan by a specialist diabetic nutritionist, said I should eat 6 white carbs per day, that’s another story. At that time I was on 40 units of long action insulin and 3 Glycazide (30mg each). By the time I started this diet I was down to 8.4 HbA1c and used to cry every night because I was in despair as to how to get it down. Testing at home I was running at10.0. About 5 days into this diet I was down to 6.9. Less than a week after that I was down to 4.8 and I freaked out, I did a post on this forum saying what am I doing to myself, I was really scared. By this time I had reduced the insulin from 40 units to 37 to 30. This trend continued and I was cutting the insulin by one unit every 3rd or 4th day. I am now on 22 units and 2 Glicazides. I found that I was having what I would have once called a hypo in the late afternoon and soon learnt that Glicazides can cause that which is why I reduced that med.
I have spoken to my doctor about how to get off the meds and he said to keep reducing the insulin first of all. Unfortunately, after 11 months on this plan I keep having slip ups like the fact I have just had 3 holidays in 3 months and try very hard but the alcohol creeps in and I think what the hell, I am on holiday so, although I dont touch the carbs I have a few treats. This has not affected my blood glucose much but I do keep losing and regaining the same 5 or 6 lbs which I will continue to try to lose. However, I have lost 1 stone 4 lbs (was nearer 1 st 9 lbs) and still have over a stone to lose.
My advice to you, from experience, would be to go back on the insulin, you can stay off the Metformin as long as you are sticking to the now bad carbs rule. Then as you get further into the plan, lose weight and see real BG results i.e. HbA1c results lowered, reduce the insulin bit by bit, one or two units a week. More important is to monitor yourself closely, testing at least twice a day, morning and evening. If you feel shakey or have the usual symptoms of a hypo, test again. If your BG is really low then have something to eat to bring it up. Prior to BSD I used to have something very sweet or carby like a jam sandwich, which meant I could never lose weight. Now I have a couple of prunes, a slice of ham, a couple of spoonsful of full fat Greek yoghurt or a square of cheese and re-test after 20 minutes. Yes it is scary but what is more scary is that no-one told us we could do this, we have been given bad advice for years so when you find something that works like this it is a bit of a shock. Talk to your doctor about your intentions to be on this diet and to get rid of the insulin and ask for his support and monitoring. I have a HbA1c every 3 months because my doctor insists but I live in France and I understand they restrict the full test in the UK. Good luck and please keep yourself safe.
