I've experienced a horrible lantus hypo. Your DN has probably never heard of it and you have to google pretty deep to find information about it. As far as I remember, the science behind it is that Lantus has been made long-acting by making it react with fat cells to form chrystals. Those chrystals are then slowly absorbed, making the Lantus last for almost a day. (correct me if I'm wrong. I didn't look it up again, but it is something like that) Now if you hit a small blood vessel, the insulin doesn't have time to form chrystals and acts like short-acting insulin. Let's just say I'm happy I've woken up again. I think I was lucky that I had a late meal that day with a lot of carbs and fat. When the hypo hit I managed to get a lot of sugar in me before going unconcious. Woke up some 2 hours later, still hypo, and ate more. Spend the rest of the day googling and informed my DN that I wanted another long acting right now.
Why would it not? I'm very active and haven't had issues with either Levemir or Tresiba. I can exercise with no Novorapid active and stay perfectly stable throughout
On days that I'm very active (my activities are irregular, so I can't really adjust my basal to that) I might need to eat (half) a slice of bread without bolusing after about 4 hours of hard work, and again after 6 hours or so to counteract my basal insulin. But I would have wanted to eat lunch anyway, so I tend to save part of my lunch to eat when my bs is slowly dropping. Works fine for me. I don't need to take a break for it either, the bread just sits in my pocket and I take a couple of bites when needed.
