I was put on this when I started multiple injections and struggled with it.
According to my consultant, this is a great insulin but tends to 'dump' at around 4-5am which can result in more frequent hypos.
I was finding that to get the right morning readings, I was hypoing a couplke of times through the night then had the rebound highs in the day - a vicious circle!
Since then I have tried Lantus (not a fan, weight gain and similar hypo issues though never told to split the dose so this may have helped...)
Now taking Levemir (30 units) at night. Only hypos I have had overnight have been due to overcorrection before bed with Novorapid.
Now on the waiting list for a pump!!! (Fingers crossed!)
