One thing you might try is to sneak up -- try injecting HALF your dose before dinner, then correcting later, if necessary. Half is better than nothing!
No. But if I'm in the low 70s, I might take the insulin a bit later, and/or eat a bit earlier, and/or have an extra snack, depending on everything that's going on. And I make sure to test until my levels get to where I want 'em.Are you sometimes afraid of an episode of hypoglycemia and don<t take your insuline in order to prevent it?
