I really cant stress enough that the “units” of afrezza aren’t the same animal as a unit of injected bolus… it just works differently. I wish they’d called them something different but imagine the FDA wouldn’t allow it. Afrezza works by quickly allowing cells to absorb glucose whereas injected works by slowly allowing cells to absorb glucose over a much longer period of time… in one instance you have to get the dosage just right, in the other you really don’t have to be anywhere near as precise…
To be successful using afrezza you have to “unlearn” a lot of the rules you had to learn to play by with injected… in doing so you can find a great deal of freedom
