I know of someone who won the jackpot which was shared and I think they got £2.2mil or something like that. It ruined their lives though. The husband ended up ripping the family apart by sleeping with women left right and centre, and the son developed severe agoraphobia due to the stress and hasn't left the house for over a year now. The daughter however spent a lot of time working for charity and has done some pretty amazing things thanks to having money at her disposal. So it really depends what you do when you win, but I think that kind of money is very much make or break.
Yup, my friend won it. Was a 10 million rollover, he decided to ring up his boss and tell him where to shove it and spend his money in his account on expensive champagne to celebrate ... turns out he only won a fiver!
Not a family member, but a girl at tennis club. I went round her house one day. It was a two bedroom semi. I went round her the next week and it was suddenly a 7 bed mansion with a swimming pool. She didn't say anything!!
