I’ve had a gambling problem all my life ever since I was a teenager. When the £500 machines first came out I won a few jackpots same as you, and then one month I blew my entire months wage one Saturday, the day after payday, playing one particular machine, think it was Monopoly, it had a wheel that you could spin with prize amounts on it, one of which was £500 i think. It had me transfixed for some reason.
A few years later I had a job where I had to drive around the country, every service station I went past I had to go in and play the fruits. Must have wasted hours and hours and thousands of pounds that I didn’t have (using credit cards and loans). Caused me to lose my first true girlfriend, and ended up having to go bankrupt in my mid 30’s.
I still play now online and at the services and sometimes the bookies, but I seem to have gone past the point where I would empty my entire bank account. I know it could easily happen but I have managed to survive reasonably ok for the last few years. I know I have still lost a ton of money but its just so hard to quit.
