Do you actually spend that much money each month?
Once we've paid our bills and accounted for our savings we don't spend that much anymore. We used to spend an embarrassing amount on food, wine and going out but thanks to some fine inspiration from the wonderful Curious and Houdini (and others!) we've drastically cut that expenditure. Getting fit has helped reduce our spend as we're not eating or drinking out often. Outside of bills, food, savings etc I think I'm spending around £50 a month. Scary compared to what I used to waste spend.
I'm not prying as to actually what you spend and what you spend it on, the other threads have just made me think about how people spend their money which makes me think about how I waste mine.
