I'm feeling a little dizzy on Atkins, what to do ?

On a daily basis I eat only meat, oil, er, eggs, half an avocado, a little cheese and basically that's all. It's true I can have unlimited portions of meat and fats, but it starts to be painful.......It's the first time in my life when I'm drooling to eat a juicy apple. They said I won't be hungry, well I'm not, but it's a very strange feeling, like I've lost my vitality or I don't know how to describe....somebody felt the same ? The results are worth this sacrifice ?
