We have a few people who have dealt with hypoglycemia on here and I'm sure they'll pop on eventually.
I think the first step is to cut out grains and sugars (refined). Go ahead and eat more often at first, if you need to, but be sure to include plenty of fat in your meals (the good fats, olive oil on salads, avocado, fat from good meats). Eventually the point is that your body will learn to burn fats for fuel instead of carbs which will help prevent the hypoglycemic ups and downs. But people who have had serious hypoglycemia will have better suggestions.
Have you tried using the search function on the forum and searching 'hypoglycemia'? I am betting you'll find several threads with some good info in the meantime.
