Yarn diet, cold sheeping, whatever you call it - I must do it!

I've bought 46 balls of yarn this month. 46!!! I am supposed to be destashing. It seems I've had my little rebellion but now I vow not to buy any yarn whatsoever until 2012. I was thinking about banning myself from swaps too but I think that might be too harsh. I'll have to reduce my swapping activities though and see how it goes. The yarn diet is non-negotiable :)
