I used to do that until I switched to Humalog. If I inject and don't eat within about 10-15mins I start to majorly crash. Plus, with my food not seeming to work properly I'd be worried about it not working in time. I have been doing it this way for years. I don't know why all of a sudden I'm noticing a big change in my treatment of hypos. I have taken post meal BG readings and they have been ok?
When did you switch to humalog? I find the same, I have in inject as I eat or even just after. If I inject before I crash too! And interestingly I get the indigestion thing too. My DSN actually advised me not to inject humalog earlier so must be a known thing?
@Ratty_Kat Have you tried eliminating wheat based carbs from your diet and seeing if the bloating/indigestion subsides? What you've described happens to me when I major on the wheat based carbs and subsides when I stop with them.
