We have difficulties with our tenage son on yom tov, trying to figure out how to bolus for those every so often yom tov treats such as Tzimis, stuffed cabbage, a roast likavod yom tov cooked up in a sauce that probably has 90 carbs for every 8 ounces of sauce etc…
Rabbi Meisels of FWD has been a trmendous resource for over 10 years, and despite his advice and encourangement my son has blood sugars over 300 a few hours after the seudah almost every time.
My son has also been to several shabbatonim Rabbi Meisels has made for boys and has come back with soooo much chizuk after each one. He is a malach (his Rebbetzin too).
