I'd love any ideas and help for this too. Someone once suggested whatever it is to tell yourself to wait a week and if you still HAVE to have it by then you can go back. It has helped for some things b/c at times have: forgotten about it, been able to reason through whether it is really needed, or if can actually afford it (LOL-not usually the case) during that time but several times it hasn't helped at all. At least it has helped with some things and thankfully it's one less thing to feel guilty about.
