Gambling addiction is the toughest problem for a gambler but unfortunately, they don't know how to solve it.
It's not that gamblers don't know but I think a lot of them underestimate their own issue so they wouldn't focus on it as much as they should before it gets worse.
On the other hand I think blocking yourself from watching football matches is extreme. Sports is something very healthy for people, and competition is cool. I wouldn't do that so.
As a sports bettor, it's understandable as sometimes you're better off not watching any games than getting tempted to gamble if you still allow yourself to watch games from time to time.
