ah yes, the perils of hypoglycemia. I'm a sufferer and it's a real *****.
You can control the lows by eating properly - balance protien with a carb and fiber. fiber is really the key - it takes longer to break down in your stomach, so if you eat fiber with protien, your blood sugar levals will stay higher, longer.
Breakfast is also the most important - my nutritionist says to eat within one hour of waking up. Like a peanut butter sandwich (on whole wheat, of course) with some fruit - pears, apples and such. I was told to stay away from bananas because they break down into sugar so quickly. Or you could use one in a fruit smoothy - just be sure to add lots of protien powder.
Eating often is important. Try eating some almonds with a cheese wedge and some crackers. Or fruit and cheese, or beans and rice, or a half a sandwich. Some sort of protein, carb, fiber mixture. Otherwise you are in a constant battle with blood sugar spikes and then crashes, which really suck.
Save the orange juice, fruit juice and other **** for an emergency fix - and then get yourself to a turkey (or tofu) sandwich in short order.
I'm learning to control it, but it's all about eating correctly. And not drinking too much caffeine, which can exacerbate your sympotms terribly.
Not as much fun as a snickers bar I know, but eating right is really the only way to stave off the eventual diabetes - which is even worse!
