What are you spending your Euromillions win on?

So obviously I will win the £181m Euromillions tonight. But if weirdly, I don’t, how would you spend/save/setup yourself with that money?

My thoughts are:

£100m in a fund giving me between 8-12% a year so on average £10m less tax to live off gives me about £500k per month.

The remaining £81m is for house/family and playing around money…but it needs to last me 5 years so I don’t touch the other nest egg so it compounds.
