Hi Fetchmeacoffee,
I haven't tried split dosing , I cycle into work so it would not be good to use in the am. I've only twice had a hypo using insuman but both times were my fault. 1st time I didn't shake it and the 2nd time I injected straight after press ups and I went very low.
One feature I don't like about is it must be kept below 25 C at all times , not sure about other basals, but this was a nightmare in the summer heat wave and it spoiled on a couple of occasions.
