When it comes to gambling, the mixture of money, drugs, and alcohol is undoubtedly dangerous. It can impair our judgment, resulting in bad decisions and even dangerous situations. Even if people don't have millions of dollars to lose, they can still make rash decisions and lose more money than they can afford. It's like an endless loop: the more we lose, the more we feel compelled to recover our losses, which can lead to even more rash decisions.
Which is what we should keep from this story as a lesson: anyone who's combining anything that was mentioned earlier during gambling is bound to eventually lose all their money. As I already mentioned, the most important part of this story that concerns us isn't that he actually lost $3 million, but what habits and behaviors to avoid during gambling. You don't need an abundance of money to lose everything, and I'm guessing that the majority of us here cannot afford to be as reckless as Dana.
This must be a big lesson not just for him but for everyone here who are fond of drinking while gambling. Just like Dana said, drinks are offered for free but it does not mean that you need to drink while you are gambling. So it’s actually having your own discipline so you won’t get drunk and will stay focus on your stake. However, I believe not everyone is good enough not to drink but the fact that alcohol will create a dizziness effect and will get you off from your consciousness, then it’s a must to avoid drinking while your are gambling. Otherwise, you will end up making worst things out of your consciousness and eventually regret in the end.
Let put it this way mate, you don't drink alcoholics that have high chance of getting someone drunk, because when we use the word Drinking it can be water, fruit juice, wine ,whiskey, etc. So the best opinion as you have given is not getting drunk while gambling.
It normal as the big guys are fond of drinking while they gamble but you the low guys only get drunk when they lose. In essence the message Dana was passing out but seems most persons didn't really get, is for gamblers to build discipline so as to avoid Ill situations from gambling.
Imagine it was someone else (poor, middle class) that was in such situation it would have resulted to suicide, depression, emotional disturbance. So by all means Moderation and Discipline is needed as a gambler. Because it takes only a system to conquer another system, so as to make you the master of the game and not been played by the game.
