Sorry to confuse you man,
If you handle a hypo perfectly you shouldn't need to take insulin because you should have eaten the exact right amount of carbs required to bring your sugars back up to 5.5mmol/L
So when your low, you need to eat something to get back up, but if you eat too much you need insulin to keep you from going too high.
Its a balancing act. Insulin makes you low, sugar/carbs make you high, and you need to stay right in the middle. So even though your numbers are low you only need A LITTLE bit of sugar/carbs to float back to normal.
Certainly discuss it with your doctor and start writing things down, it REALLY helps to sort this stuff out because you can look back and say "2 weeks ago I was at 3.2, and i drank a whole juice box and went up to 10.5 two hours later - ok, this time I am at 3.2 I will only drink half that juice box (or take insulin to counter the other half) and should end up around 6.5"
This is what the forums are for! The best thing you can do is test, remember what happens /write it down, and then try again next time and adjust for the mistakes from that last time.
You'll get it, it will get easier and before you know you it you will be able to handle it all without even having to think, you'll just know, like instinct!
