Pleased about your win, I do hope you don't just chuck it back in, the temptation is there. Turn your PC off, get some sleep, wait for the money to hit your bank account and enjoy.
Never get hooked on it though, it is a drug. If you are disciplined you'll be fine. I'm a Casino bonus abuser, made a fortune from Casino's over the last 10 years and always maintained discipline even when on a losing streak. Even during that time I've never managed a £1k+ win from a spin, biggest I've managed was £500 a few years back.
