Reactive Hypoglycemia........need help!!

Options
I have hypoglycemia and crave sugar constantly. Its a constant battle not to eat everything sweet in sight! I gain weight extremely fast if I consume sugar. Simple carbs also have a very negative effect on my mood and my ability to think clearly. So I need to stay away from sugar and eat every 2 to 3 hours or so. Is anyone out there struggling with this same thing? Any success???
