Thanks for all the suggestions guys

I tried claiming off my insurance matt - but they told me I needed a policy first

I thought about buying a new carpet SS - bugger that!

I gave the coke a miss jeera - for the time being anyway (I have enough stains already!

)
Darn, the stain is already dry graeme - but I think it's a sensible suggestion (ok ok I was drunk and went to bed and it dried :-[!)
Milton - yes, that's a bleach for nappies isnt it? - kids are all grown up (might try that later though)
I'm reluctant to try bleach (or peroxide) parker - it might end up white!

Kill yourself BB? _ I tried that and that didn't work!

I tried Vax carpet cleaner - nope
I tried vinegar - nope
I tried baking soda - nope
I tried Vanish (thanks UB) - didn't seem to do much (maybe a little?)
I tried lemon juice - it seemed to help best....well, made it lighter yellow!
So far, it seems that lemon juice and ultra violet light might do the trick - ever hopeful! (I just need a sunbed now!)
