@kaylz91 Hun cut yourself some slack, that's nothing to worry about, not quite sure where this lad gets his online knowledge from but until he walks in your shoes then he's got no idea what your dealing with, maybe when he gets a PhD then he will start to come close but until then ignore his comments. A post meal spike is typical for diabetics, some will pre bolus by say up to 20 mins to counter it, but the most important reading is your pre meal test, as long as you are in range again at this point then your bolus calculation was correct and did the job.
