Hi Dancer, The problem when setting a temporary basal is that sometimes I hit the jackpot and need very little extra insulin (relatively) but on other occasions I need a lot. Difficult to predict. Advice from Endo was to have evening meal bolus for that correct if necessary 2-3 hours later, do the set change and then not have anything to eat until breakfast and then correct before breakfast, wait an hour or so and then eat. If I wake during the night and it is higher than it ought to be I will correct then. Experiencing some success with the infusion set on the outside thigh but it is still fairly random although I think I need less insulin to correct but not consistent enough to use a temporary basal. Diabetic 45 years and degree of insulin resistance to deal with. Helen@Helen46 have you tried using an increased temporary basal when you change a set? I use a decreased temp basal for 2 hours after changing sets which prevents me going hypo (I am insulin sensitive). I have read on the forum that some pump users require an increased basal to prevent hypers after a set change.
