Well he was 17.9 when he came in from school (3.30) and at that point had 16u Humilin S. He would then have started snacking, crisps, cereal bar, cheese & crackers, I don't exactly know what, but anything he could get his hands on. I have put away the majority of 'spare' lunchbox stuff but left an odd pack of each thing out in case he needed something in a hurry. We would normally then eat our main meal around 5.45-6pm but we were a bit later that evening and he tested at 6.30 just before eating, to find he had dropped to 4.7 despite snacking in those 3 hours.
Dare I confess we then had chip shop? He had donner meat and chips. He didn't test at bedtime, so unfortunately I don't know what happened after dinner, but his friend came over and they went out to the shop across the road and I wouldn't be at all surprised if they had come back with a load of chocolate between them. They just disappear up to his room complete with carrier bags (always with a bottle of Pepsi Max in but no doubt more than that) and that's the last we see of them for the evening.
Anyway, on waking the next morning he was 11.4. He would have had 30u Lantus at bedtime too (and I know he did, I am keeping an eye on levels in pens).
I guess with this erratic eating though, we are never going to know really what exactly is going on. He hasn't been anywhere near the 4's for quite some time though, so at least the doses of Humilin must be getting somewhere near where they need to be. I don't actually understand how the Humilin S works, and there is nothing useful in the leaflet to tell you either.
Unfortunately, he didn't test on coming in from school last night though, nor before his dinner, so I only have this one set of figures. Dinner tonight will be a much healthier affair with plenty of vegetables etc, so it will be interesting to see how his body copes with it. I will keep a watchful eye.
