My now 6-year-old son has been having episodes upon waking in the morning, which were happening about twice a year, but have increased in frequency to once every one to two months. He is lethargic, extremely weak (explained by him as having no power), and is very pale. Every time this happens, he will not wake on his own. Nearly every time, something sugary with recover him quickly, although sometimes he will vomit before we can even make it to the kitchen.
