If reason prevailed over feelings, we would not see a huge number of addicted people, and not only in the field of gambling. Only a small part of gamblers can really control their compulsive desires, imposed by the release of dopamine, adrenaline and other hormones and neurotransmitters. Most can control themselves before and after the gambling session, and during the gambling session succumb to temptation. This is the way the human body works and it is difficult to cope with it, especially if a person has a predisposition to addiction on a psychological level.
