On the one hand, if an addicted gambler won a large prize, there is a good chance that he will soon drain it back, and at the same time, the entire deposit.
Indeed. I even doubt that addicted gamblers can enjoy the prize even if they win a large prize. They probably will dream to win again and again bigger prizes. So, they may have no idea to stop temporarily enjoying the prize. True, they easily drain it again soon since they are trying chasing more wins. For me, enjoying the prize is a must. It can make us more comfortable and it can be a good booster of our mood.
That is correct, and that is also one big sad thing about all of this. People actually believe that they will enjoy it and some even use it as an excuse to continue their bad behavior. However it is not possible to enjoy it, biology does not let you. At best it will be a very short high feeling which will dissipate fast because of the addiction. That is also one of the reasons why big winners ruin their winnings, it does not feel good as they expected
