60-100U, depending on many things.If I have a good low-carb day (<100g), I’m usually in the 60-80 range.
Indulging in a gourmet burger and fries can burn through a scary amount of insulin though. I don’t do it very often, but I did go to Betty’s Burger in Santa Cruz, CA, on mother’s day with my family (my wife loves Betty’s). Keep in mind these are not your average burger.
Anyway, almost stayed in range – drifted over 140 to 146 for a half hour or so – post-gastromomigasm, but the amount of insulin I have to use for adventures like this would kill a (sensitive) T1: 30U administered 35 minutes before starting to eat, then another 20U administered in a square-wave bolus over 4 hours when I take the first bite.
That’s a total of 50U. My I:C is 1:5. Yet, the meal did not include 250g of carb, not by a long shot. Between the bun, cheese, condiments, and fries, probably more like 120-150g.
And yet, no hypo. This is a phenomena I’ve learned well, and I believe is a T2 IR problem. My IR seems to have carb load as a variable in insulin response, even when my BG stays controlled, seems to “peter out” with big big carb loads.
Last time I indulged like that was over the holidays. I refill my insulin prescription on a 25-day rotation (generally you can refill prescriptions up to 5 days early on a monthly cycle) so I can build up a bit of reserve for Zombie Apocalypse, and for indulgent events through the year like this.
