You need someone that will help you losing the addicting. Or get into sports,not sports betting.
Someone that controls you and keep you away from the gambling websites.
Block yourself from accessing this websites.
I like that "sports, not sports betting" line of yours. Haha.
It's an effective way to stop addiction to gambling.
Although, it's very difficult to do it.
But always remember, successfully starting it means you are already halfway there.
