This is driving me nuts. I am hungry all the time. Once I eat, I need to eat again within an hour and a half or two. I ate cereal and grapes at 9:30, but was starving again at 11:30. I had a sandwich, apple, and some crackers, but am ravenous again (12:45). What can I possibly eat that will fill me up for more than two hours at a time? I start to feel nauseous once I get hungry, but I am sick of eating all the time.
