One day you could take 10IU and experience no sides what so ever. The day after you might take 5IU and experience hypoglycemia. Wondering why? I will clear this up for you just incase you are interested.
Hypoglycemia not only depends on how much slin you take, and how much carbs you consume. It also depends on how active you have been throughout the day, it depends on your diet for that day as well as how tired or energytic you have been feeling. All these effect BG levels, and using insulin + carbs PWO on top of that will effect BG levels as well. So at the end of all this, depending on your daily schedule + slin/carbs PWO depends on where your BG will end up. And at last, depending on where your BG is depends on if hypo will be absent or present at that time.
That's why sometimes people get confused and say "
hrmm, yesterday I only took 7IU and had experienced hypo, but a while ago I took 15IU and felt fine". What's the deal there?
Hope I've made that clear.
