Hi Rosa and Mimi, I haven't posted before, but I have been following Mimi's progress for a few days. Bron will be asleep now so I thought I'd try and answer your query.
With Lantus, when you skip a shot it drains the depot (
link to info on depot, please follow it and read if you haven't already), so you won't see the full effect of the dose until the depot starts to fill again, so it make take a couple of cycles before you start to see what the dose will do. (for George that would be cycle 3 or 4).
The drop into the 50's when Mimi was on 1.5u tells us that 1.5u was to much, so you need to first see if this new reduced dose will hold, and for that we need to wait for the depot to fill. As long as she is not throwing ketones I would hold for now, if she was throwing ketones we would need to pursue a different strategy.
I can't see a ketone test for today/tonight,
I would make it a priority to get one.
Do you think you could note on the ss when you are feeding and how much. You could annotate it on the grid with an * and then note in the comments what you fed and how much at each particular feeding, it might not seem important now, but it will help you in the future if you find it becomes necessary to alter food intake to manage the curve. I always made not of what I fed and when it helped me devise a strategy that worked for George, and more importantly helped others help me when I was starting out.
