Ban yourself, legally. State by state.
Self-exclusion is the single most effective step in the research: you sign once, and every regulated casino and betting app in your state must turn you away and stop marketing to you. In the strongest study, people who combined self-exclusion with blocking and bank controls had essentially zero relapses. Here is exactly how to do it where you live, verified against the official state programs.
