I am picking up a sample vial of Apidra tomorrow and was wondering what the consensus is on how Apidra works when changing from Novolog/Humolog. I am currently using Novolog and it lasts approximately 4 hours in my body and I usually need to prebolus meals by about 15 minutes. What changes should I expect? Will I need to change my basal rates or bolus ratios? Does TDD change? Anything else that I should be aware of? Thanks in advance for the info. The vial will probably last me about 1.5-2 weeks and I really don't want to spend those 2 weeks fighting highs and lows if I can avoid it.
