Foolproof way to get sugar out of your diet?

I know I eat way too much sugar every day
even though I know how horrible it is for your
health! I might as well be addicted to a drug.
I don’t know how to even start to get myself
clean of sugar. Can someone give me some
ideas…I feel like this has taken over my thought
processes and I just cannot talk myself into
understanding how bad it is for you.
