Im the same. However I think its not all due to my personality disorder. Sometimes Im just a bit unorganized. I like the idea of taking cash out at the beginning of the week and then once its gone it is gone. Im going to give that a shot when I get paid. Another thing I find helpful is when I want to purchase something asking yourself (if im skint) 'Do I need it'?? ''Can I afford it''. And if I am not skint ''Will I use it??''...''is it worth it''. I got these 'money mantras' from the money saving expert website. The link is below.
