Hi Jordan,
I test my blood-sugar a lot: 15-20 times per day. (I use Betachek Visual testing strips as well as the usual meter-read sticks; but Betachek Visual are currently very difficult to get hold of in Great Britain.)
But far more crucial for me is eating dark rye bread. Each morning (after coffee and a fag), I start eating it: slowly at first, as the insulin begins to kick in. (I eat it with pear and apple spread; but any suger-free jam or marmalade will do.) I eat a little under 200g of it per day, mostly in the morning, but I continue eating it until the mid-afternoon. This is what keeps my blood-sugar stable. Without it, hypos would be a regular thing for me. (Nb. I have to be careful not to eat too much of it or my blood-sugar will go high later in the evening.) I wouldn't particularly want to recommend Tesco, but they do at least sell pumpernickel - a form of dark rye bread.
Of course I still have to be careful. But if a hypo does happen, it's no longer like falling off a cliff. I get a decent chance to recover myself.
Another thing of major importance for me is that the effect of the insulin I take is running out by the time I go to bed. (If you want to change your insulin regimen, you would of course need to consult your GP first.) So unless I make a serious error, a night-time hypo is practically impossible in my case.
I'd be happy to respond to any specific questions you may have.
