We can lose control when we drink alcohol, and if we play gambling, that can make us get serious trouble, which is we can lose the money.
I agree with you. Drinking alcohol during playing gambling isn't good behavior. How can we focus to play gambling if we become unconscious because of alcohol? This is the wrong thing and should be avoided to do. If we think we are wise and smart gamblers, we won't plan to have alcohol while playing. It is not only harmful to your money but also risks your life.
