I've seen several references to other T1/LADAs who say when they were diagnosed they initially needed only basal, but no bolus. I'm just the opposite. I need small amounts of bolus, but my pancreas is still covering my basal needs. If I skip bolusing for a meal that needs it (e.g., >20g carbs), I'll go up into the 200's, but will come down by the four hour mark (which is why I only skip if it's a low carb meal or I'm going to be exercising after I eat). I'm curious if there are others out there like me. I'd also love to hear from the science minded folks why they think it might be that some folks need only basal, but others need only bolus. I know it may simply come down to the fact that every individual body is different, but I always love hearing the theories you all come up with.
I've just assuming that the advertised duration was about 4 hours like the manufacturer says was accurate for me. Haven't really thought about the possibility it could be lasting a lot longer than that.-- It'll be easier to get a better feel for it now without the lantus affecting things as well. Good pointer on something to look out for. When I'm at home I try to space me meals a little better than is working out here. Breakfast is only about 4 hours before lunch here, normally I would go at least 5 hours... The picture is very slowly starting to get more clear with all of this.
I've experienced the same thing with Apidra, but I don't think I can be sure whether it's the tail of the Apidra or some effect of a sluggish pancreas still kicking out insulin, but not necessarily doing it at the right time. With whole blood glucose control mechanism being out of whack it is indeed difficult to pinpoint the true issue.
Thanks, this is very good info to have. I was thinking of a CGM, but I'm afraid I might start to obsess even more than I already tend to do. I tend to need more insulin for lunch than other meals and that's with only a four hour break between breakfast and lunch. I wonder how much more I would need if I went longer -- that might explain why some days I go higher with the exact same meal at lunch than others. Perhaps on those days, I ate breakfast earlier than usual and that bolus was completely gone. Not exactly the kind of mysteries I'd like to be solving, but I guess I'll probably be a blood glucose Sherlock Holmes for the rest of my life.
I use slow and fast insulins together every 12 hours so overlapped 4 ways. The slow starts in 2 hours and lasts 8 hours and the slow starts in 8 hours and lasts 24 hours. Compared to modern analogs even my fast is slow so today this could be seen as all Basal. It works well but I have to plan ahead by at least 12 hours. T1 for 53 years and doing great. I still use the exchange system for diet and have no idea how to count carbs and never will.
Everybody is different and this fact is never understood by any breed of doctor.
Thought those who participated on this thread might find this article interesting: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2901038/
Not sure that it adds anything to the mix, but at least I'm understanding a bit more about what's going on with my pancreas as far as first and second phase insulin release. I ended up finding this article while researching that issue.
Very interesting article, Shawnmarie. Thanks for posting the link.
Thanks for this article... I think I was struggling with 'reactive hypoglycemia' for years before T1 diagnosis..
Thanks for pointing me towards this thread - wow, it's been so helpful to hear about others' experiences with low insulin needs.
I think I smiled the most about reading about another adult using the 'junior' pen to get 1/2 units. The instructions do say it starts at 1u, but I did some 'tests' dropping insulin onto a plate and it seemed to provide a uniform volume of a 1/2u and I've been using the pen as such ever since, ignoring the childish green frog on the package that made me think it was only for kids.
I got one last month, but ended up suspending my Novolog experiment because my I:C was fluctuating like crazy and I didn't want to add another factor. I like the looks of the kid pen!
