The moment you begin to feel like you are playing too much, you should immediately take a break. You can take an online test to see if your gambling is becoming problematic here. If it is, then there are several options; you can reach out to an organization that can support you in controlling your gambling.
Organizations can be found here depending on which country you live in. If you feel you really can’t control your gambling, then contact your casino immediately and ask them to self-exclude you. This is the best way to ensure that you won’t be able to play. You can also install software on your computer that will block all gambling programs and ads. In some countries, such as the UK and Sweden, there are national self-exclusion programs that allow you to exclude yourself from all casinos at once with the click of a button.
