Do you check conscious or unconsciously lied to someone or to your love ones to cover your gambling loses? And what kind of lying did you do? Did you tell that you just lost like $50 but in reality it's $500.00? Or that you lend some money to your friend, but then you go and play on casinos? Or you tell that your paycheck is short and there is something wrong with it and so you will have to ask your company's HR about it?
How about other lies that you uses because you can't admit to yourself that you've actually lost because it's a sign of weakness?
I think it's pretty common for gamblers that have recently lost a big amount to start lying to themselves at least and simply "forgetting" that they lost a lot, and just focus on their wins.
I've heard from gamblers all about their winnings, but they never share the times that they have lost, which are of course more common...
It's a mentality thing really.
