- I use Lucozade and count the swigs! You could, of course, measure it into a jug or whatever. Glucose tablets are also really good because you can have a controlled amount.
I know what you mean about overreacting through fear. I've done that sometimes when I've been dropping quickly. It's especially scary at night. Also, it does take a while for yoyr BS to rise, so it's very tempting to keep eating as you don't feel right. What I do is treat with initial glucose, wait 10 minutes to see how it's going, have some more glucose if necessary, then eat a longer lasting carb snack of between 10 and 20g depending on how quickly my BS is responding and what the reason was I went low.
I know sometimes there's no reason, but if I go low because I miscalculated carbs in a meal I tend to eat more carbs to make up for that, whereas if it just went a bit low because I'd been rushing about, I wouldn't have so many.
To avoid the fear of nighttime hypos, I set an alarm to get up and test again. It's a nuisance, but it gives me peace of mind and means I don't overeat to treat the hypo.
