Re: Paradigm 515 WAS RE: Hypos RE: [IPk] Paradigm 512
I found your explanation of IOB excellent and something positive to go on.
Thank you very much. Pat explained about the linear nature of it so I
understand this. I would love to get better control after a meal. I have
heard others say (I understand) that they try to get their blood sugar back
to normal after 2 hours. I can never do this. I have fasted frequently to
sort out basels and these seem fine. If I know the IOB I shall be much
happier making correction doses. At present it is purely an educated guess
and I seem to be very sensitive to insulin even in very small amounts.
