Do you suffer from regular mood swings, feeling up one minute and down, irritable or peevish the next? Can you quickly fly off the handle? 

Do you find your energy can dip and your appetite peaks, so you reach for a sweet treat or carby snacks like crisps, chips, pizza, or a hunk of white bread?

How do you get your energy going when you're feeling tired or flat? Do you tend to gulp down a caffeine-laden energy drink or coffee, or do you regularly consume sweet, fizzy drinks?

If this sounds anything like you, it could be that your blood sugar is unbalanced, which is contributing to your bad moods and energy slumps.
