Spend it as quickly as possible! I remember my brother once told me that almost majority of the proceeds he won from gambling, he considered it as "dirty money" where he must immediately spend and use it. Generally, I avoid gambling again using my winnings in order to avoid any losses on my part.

While others may suggest to gamble again, I highly advise you to spend or to treat your family members/peers with the winnings that you receive in a good gambling run. Betting again only increases the risks of losing all of your winnings, thus making it impossible for you to use it.
