My DSN worked out my correction dose as 1 unit bringing me down by 6mmol. This seems to match the table given in "Think Like a Pancreas", as I'm only on small amounts of insulin. (0.5 to 10g carb. and total of roughly 15 units of all insulin daily.)
However, that correction dosage doesn't seem to work for me usually. Before bed last night my reading was 12.2.(Smacked hand for Valentine's meal that inc. Potatoes Dauphinoise) I had my Lantus as per usual but was obviously unhappy with such a high reading pre-bed, so decided to try 2 units of Novo, which is double what nurse recommended but matched what others on here say they take as a correction dose. Morning reading shows this was spot on, as this morning I awoke with reading of 6.0. Now, the only thing which could throw this out would be if I went too low in the night.
When I tested my background insulin two nights ago, I went to bed with 8.3 reading, set alarm for 3.00 a.m.Reading then was 4.9. Went back to sleep and on waking reading had gone back up to 6.0. Now from what I've read, this could be the Somogyi Phenomenon.
I intend re-doing the test several more times before I adjust the Lantus but did not want to do it on a night when I'm taking a correction dose.
Can someone more enlightened than me, tell me why my correction dose would be twice that recommeneded by the nurse and the book? Isn't it harder to test a correction dose in the daytime, when there might be an overlap of fast-acting insulin? Is it, as I suspect, that my Novorapid ratio is wrongly half what it should be, which in turn would make the correction dosage 1 unit= down by 3mmols, correct. IYSWIM. Obviously I shall be working on Novo thing once I have Lantus spot on. I guess I just need confirmation of me tackling this correctly and clarification of the puzzling correction dose thing.
Sorry if this sounds confusing.
