That's the first I've taken them at same time. Won't be doing that again! Taking the Levemir on its own never bothers me.
Hi, I am quite new to this also, having been diagnosed about 7 months ago, but in my limited experience I'd say taking both together is unlikely to be the problem. I often take Levemir with my Novorapid and the hospital said they are fine to take together. Check it out with your nurse if you're not sure.
For me, going from such a high number to 9 so quickly used to make me feel dreadful. In my experience, this has got better with time, so whereas I used to get all the hypo symptoms with such a change (as you described) I now usually just feel overcome with sleepiness or a bit 'funny' and can't put my finger on it. The same also happens the other way around when I'm going up very quickly only I notice I feel dizzy and very chatty, bit like a glass of wine!
It's really disheartening when symptoms happen that you can't explain, and I still feel very lost with it all. But I thought it might help to say this happened to me and it's got better, so it might get better for you as well. Fingers crossed x
