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.
Well, that's true. Spending it will also serve as a remembrance that you had a good win in gambling. We know it's not often happening because we usually lose than win, so make the best out of it if you had the chance. Playing again is not advisable, as you've said it increases the risk of losing your winnings. But I think there are gamblers who don't stop because of their greed to win more and it's not new actually. They will realize their mistakes after losing their winings, then will have regrets in the end. I experienced this before thus everytime I win even small amount, I stop to avoid losing my winnings then return back after few days.
