I switched to apidra after trying all three analogs, because I found it works a whole lot faster for me. It finishes acting in 2.5-3.5 hours, with an action "half-life" of 1.5 hours, very consistently. I have DIA set to 3hrs on my mm pump. I think with Humalog it was 4-5 hrs (but I was on MDI then).
