Mo money, mo problems

I've been working really hard to reign in my spending. I've been doing somewhat better, but I still spend too much on silly things.

It has worked fairly well for me in the past to compartmentalize things. This is why I have so many bank accounts. I think I may need to split it up further. Here's how my split sits right now:

Joint bank account (rent, gym, other joint bills): $500/paycheck
US Bank account (remainder): $1000-ish/paycheck

Out of my US Bank account:
$425/paycheck - Car or Student loans
$250/paycheck - Savings
$40/paycheck - Gas
$10/paycheck - MPR Membership

This leaves me with about $400 or so to play around with. I tend to blow through this, especially when things like groceries are purchased.

I'm thinking I need to change up the split a bit more...

Joint bank account (rent, gym, other joint bills): $500/paycheck
TCF Bank account (fun money): $200/paycheck
US Bank account (remainder for bills and stuff): $800-ish/paycheck

Then I can only spend the stuff in my TCF account... I dunno how this will work, but I might want to consider splitting my paycheck up like this automatically and see how it goes for a while.
