How does a sugar addict give up sugar?

Ok, it sounds like a really stupid question however for someone like me who has never had an addiction before, I am really struggling with giving up sugar and dieting. I get really moody, my body aches sometimes and I lack energy without it. To make matters worse, most fruits are extremely high in sugar so there is not much one can consume and lead a decent life:-(

Any tips?
