I have low blood sugar (and also low blood pressure), and I know exactly the symptoms you are describing! The "quick fix" is juice and a candy bar, but I always try to follow it up with some carbs which will release back into my system slower, and for longer. I usually have a glass of orange juice with some sugar stirred in, and then have a cheese sandwich, some fruit or similar (nothing big - just to compliment the "quick-fix"with something which will keep me going a bit longer).

The problem with low blood sugar is that you can get into a kind of "roller-coaster" effect, and when your body uses up all the sugar from the quick-fix you go into a real SLUMP and feel even worse than before.

I don't take any meds for that, or for my low blood pressure, but I find that having smaller, more frequent meals throughout the day helps my sugar level to stay constant. Also try not to skip breakfast if you can help it.

It IS such a horrible feeling, and you have my total sympathy!
