The weird readings today started at lunch. I was 5.7 at breakfast and had the same breakfast and the same amount of insulin as normal and can generally set my clock by a similar reading 4 hours later. The only difference in what I did today was that I had breakfast at 7.30am rather than 8am.
I was surprised and alarmed to come in before lunch at a hypo-level 3.3, so I had my lunch and tested again. I was still 3.3. I ate some chocolate and tested once more about 15 minutes after and this time I was 4.9. I took my planned 4 units of insulin hoping the chocolate had acted as a reset and the lunch would be back to normal. I felt absolutely no ill-effects from being 3.3. Not a flicker. That was also weird as I’ve been shaky at 4.1 before.
Whenever I get a setback like this I focus on what I can learn from it. The following is taken from the website medbroadcast.com/drug/getdrug/novorapid;
“Insulin aspart is a rapid-acting insulin. It takes 10 to 20 minutes to begin working after the injection, has its maximum effect between 1 hour and 3 hours, and stops working after 3 to 5 hours.”
I usually have lunch 4 hours after breakfast, so it is possible (probable) that there is a further 1 hour of effect to be had from my breakfast insulin. I will need to adjust for this if I eat after 7am and also bear the breakfast insulin might still be killing carbs when doing my lunch calculations. This explains why I calculate my lunch insulin and often go low anyway. I probably did nothing wrong I just didn’t remember that breakfast insulin lasts longer than morning. This is a key piece of learning.
Tea came and my reading was 11.1 which is high. Obviously the 4 units I took at lunch was nowhere near enough to deal with the chocolate I took to deal with the hypo and then my normal lunch, which contained carbs. I’ll admit I had absolutely no idea what insulin to take at lunch and will ask the nurse about this when I see her next week.
The good news is I calculated carefully at tea and probably 1 unit away from the optimal amount and got things back on track quickly. I’m confident I know have the skills to make adjustments and stabilise. Whilst I took 14 units keen to get the levels back to where they should be, 13 units would’ve seen me come in at 7.2 roughly which would have been correct. I took 32 glargine and should wake up at about 6.0.
