@smc4761 The question is what caused the low? was it a post meal low where you've jabbed the right dose, had the meal and then gone low, probably because the carbs haven't kicked in but the insulin had? then to correct that sort of low takes a good dollop of fast carbs to counter act the already actively working IOB, then maybe what you think is the over-correct is in fact the carbs that were in the meal? Then again you may well have just over compensated but with out knowing everything is difficult to say.
On Sundays, I usually have a cooked breakfast and skip lunch so by mid afternoon I've no IOB and breakfast carbs/fat and protein have all but gone, if I drop a bit low I know there's no need to panic, it's not going to drop significantly any time soon and I can take 1 glucotab to keep me bumbling along if I'm not doing anything too strenuous.
