I have no credit cards except for my debit card. If I have extra money left over in a month I give it to my daighter to keep for me.

If there is something large I want to buy, I discuss it over w my daughter and we both agree before she hands me back any money.

I don't have space in my apartment for a whole bunch of stuff and don't have money for those spending sprees.

This arrangement also helps with my tendency to hoard.

I also get new interests and then want to keep buying everything I can to support that interest, with no space to put the stuff. So this arrangement helps with that too.

I have also found that when my desire to spend spend spend is totally overwhelming that if I take my prn seroquel, half an hour later I will experience relief and can then be more rational about it.
