I don't know how I did it but I managed to spend under £600 during my 2 weeks in Ibiza last year.
I went to all the big nights, Manumission twice, Space 3 times, Cream, Judgement Sundays, Ministry etc.
I think the way I got away with it was I'd would always buy my tickets in advance with flyers which is worth it just to get the free drink in most cases.
Also alot of the clubs will stamp your hand so u can leave and come back which is great if u prefer paying 50p for a bottle of water instead of £5.
Its easy to smuggle bottles into clubs but if u get caught I hear u will get kicked out and maybe even barred so It's not really worth the risk.
one last tip - looky looky men are selling the cheapest 'things

' on the Island if u bargain with them and they don't f*** u about like alot of the dodgy people in the clubs will.
This year I'm taking £600 again and my bank card, I'm sure I'll need it.
I'm a student - is it that obvious?
