I hate hypos too! Sometimes I test more often than the recommended 15min because seeing my numbers stabilise/go up helps me realise I will be ok, and not try to have more sugar. For very low numbers (like <3.6) or fast drops, I test every 5min until I'm feeling ok about it. I use my intuition a lot though, sometimes I feel like I simply must have a second juice box and so I do it, usually when I get these feelings I am right! (my blood sugar only raises a little bit).
