As a pro poker player most of my adult life I've gambled a lot and seen many people make crazy gambles on all manner of things.
It's very hard to stop if it becomes a problem or even if it doesn't. But if you are someone who is losing a lot through gambling then the most important thing is to seek professional help.
And if that just doesn't work you need to find an outlet where you can gamble with an edge, like in poker. If you're good enough you can make money there while still gambling lol
