I use apidra in a pump and switched from humalog but I barely noticed any difference and as others have said all the rapid insulins are very similar so it is more likely to be related to dosage/timing of insulin, what you are eating, your basal amount, there are a lot of other things far more likely to be causing the highs rather than the type of insulin you are using so it would probably help to speak to your DSN and if you don't already keep a close log of foods and doses etc maybe try that to help identify any patterns.
