Have you started any new vitamins lately? I know it's a long shot but I just recently started eating like a horse myself and it turns out it was the B complex that I just started taking. My arms and hands go numb when I lay down and a buddy suggested taking B complex, the bottle said it was for cardiovascular health. I told my brother who is also taking this vitamin, that I feel like I'm starving all the time and can't stop eating, we got to talking about the vitamin and he said on his bottle it said B was good as a metabolism booster. Just a thought, and even though it said metabolism booster I was eating astronomical amounts and actually gained about 5 pounds in a week or two.
