That £150 is purely for fun things, not petrol/food/bits and bobs for living, just things like drinks, tobacco ect ect.
If you seriously can't help but spend £150 within 5 days, let alone 3, then you got issues mate

That's ok then. It sounded like you meant all your living for £150 a month. I do that on petrol alone and I only do 700 miles a month
