[QUOTE="Scott-C, post: 1716201, member: 374531"] It makes an amazing difference injecting novorapid before a meal. It's called "pre-bolusing". It takes a bit of practice to figure out timings and the timings often differ depending on the GI of the food involved. But the basic idea is that insulin takes a bit of time to be distributed around the body and get to work, so, if you pre-bolus, let it get to work, it'll then deal head on with the glucose coming in from food. Whereas if you bolus after a meal, there's going to be a spike from the food and the insulin will be playing catch up. It's definitely worth experimenting with. I tend to inject about 20 mins before a meal, perhaps 25 to 30 for high GI foods like ravioli, but only 10 to 15 for low GI, like brown rice. And I'll make a few adjustments to the timing and dose if I'm steady or trending down or up at the time. But that's just me. You'd obviously need to practice with it. Many people will eat the same sort of meal a few days in a row and extend the pre-bolus by 5 mins each time to figure out the "sweet spot". Here's a pic to show the difference it makes. Left hand side at just before 18:00, I have a 9u shot, I'm about 5.5 on a downward trend from a small 1u correction shot earlier, about 30 mins later, I have 75g carbs, can't remember what it was, maybe ravioli on toast. Instead of a spike, I get a gentle spoon shaped curve down to just above 4, rising back up to about 6. That simply wouldn't have happened if I'd bolused with or after the meal: it would have been getting on for 10 or more. Unfortunately, it doesn't always work out that way, but it's sweet when it does! [ATTACH=full]25525[/ATTACH] [/QUOTE]
