I had two hypos in one day and after that I quit insulin. So, I totally understand how your brother feels (at least about that). If you want to know how it feels, check out my blog entry on that experience. In short, being too high is not good, but it leads to a slow death-hypos (and then 2 back to back) feels like you’re going to die IMMEDIATELY.
When I have a hypo now, I just eat fruit, cake, icecream, pie, or whatever else has PLENTY of sugar in it.
Now that I’m no longer on all the medication-I was on too much insulin-things are MUCH better for me.
