I appreciate that, but it does help compared to MDI. My point was that the OP is experienced with diabetes, has had educations courses and a pump and is still experiencing quite significant problems if she feels it isn't safe to drive. It is therefore worth trying a low carb diet although I appreciate that in her circumstances with young children, I would struggle if I wasn't already familiar and comfortable with low carb eating, because it does take some getting your head around initially. I don't personally find it more fiddly or time consuming to cook low carb because I just avoid high carb foods like bread and pasta and rice and breakfast cereals etc but it took some time to find low carb things that I liked to fill in the gaps.
I would point out that I mentioned education and basal testing before I suggested low carb, so I really don't feel like I was being excessively pushy about trying low carb, just offering possible solutions.
@Inka I have seen you mention this before about Dr Bernstein. Obviously I know of him but I don't follow him or know a great deal about him. I don't know if the information you quote about him not having hypo awareness is current or just a phase he went through or misreported, but I am sure there are people who eat a high carb diet who also have no hypo awareness. We are all different. It may be an age thing which is affecting his awareness. There are so many factors which influence our levels. I haven't found that a low carb diet has affected my awareness so far and if going low carb also causes insulin resistance (or lack of insulin sensitivity) as you often suggest then there should be little concern about hypos if you are using minimal insulin. There is no harm in giving it a try.... other than the effort involved. I agree with Patti that it can make managing diabetes with insulin easier for some people but it depends on the individual, just like everything else with diabetes, we all react differently and have to find what works for us, but we do that by experimenting and trying different things.
If you want an example which doesn't involve failing cannulas, I have had 4 attempts (experiments) at eating a sweet mince pie in the last 4 weeks and despite pre-bolusing a significant length of time in advance and injecting both a normal amount of insulin for it and an increased amount of insulin to see if the carb info is wrong, because personally I think 38g carbs for a mince pie is a little low although they are smalliish, I have ended up spiking to mid teens every time and then needed a correction later to bring me down. 7 units of insulin for 1 mince pie with a normal ratio of 1:10 is ridiculous and my Time in Range stats are trashed. So my 4 attempts to get it right, tell me just to stick with my low carb way of eating. And I ate cream or cream cheese with it on each occasion to try to slow it down! I appreciate that a mince pie isn't the healthiest option but a few pieces of sweet potato usually work fine and they are part of my low carb diet, a mince pie most definitely isn't. I just prefer to stick to just 20-30g carbs at a time and find that works well for me and still provides a lot of variety in my diet.
