Message: <blockquote data-quote="Deleted member 527103" data-source="post: 2416118">I have been using Fiasp for a couple of years. My experience is - it's shelf life out of the fridge is less than NovoRapid. After a couple of weeks, it can feel like I am injecting water. - the speed at which it starts working seems to be very dependent on my blood sugar levels. If my levels are around 4/5/6, Fiasp will start to work straight away. If my levels are high (over 8), Fiasp can take at least 30 minutes to start working. This can be an issue when correcting a high (over 12) because it takes a long time to come down, even when I take into consideration insulin resistance at higher level. I have to remind myself not to overcorrect when I don't see movement in my levels because if I do, I tend to hypo after 90 minutes or so. I use a pump and, because of the second observation, I use the combo/extended bolus most of the time when I bolus for food and adjust the upfront percentage depending on my current blood sugar levels.</blockquote>
