I think you have to just treat this like any other addiction.

I feel like I compulsively play chess online. I had not slipped up from 1/1 until last night. Then I really fell off the wagon tonight and played about 10 games.

It sounds ridiculous but I just have to put that behind me and get back to not playing online chess. I can play in person for fun but not the mindless waste of time chess has become for me online.

For me at least, it is always much harder to moderate than to go cold turkey with basically anything.
