I've found the easiest way to stop doing something, whether it's visiting a website, playing a game, or something else is to shut yourself off from those things cold turkey.
Just saying, cause it seems you need to "stop" a lot of stuff, and most people I have observed are more successful at it when they just stop rather than trying to ease off of something, if they try to go the weening route so the speak, they're way more likely to never actually stop.
