Three things I've done to help control over spending:
1. Only eat out once a week, and make sure its not over $20.
2. Only buy what you NEED, never what you want. Anything over $50 needs to wait until it's on sale or if you can sell something to upgrade. (I do this with iPhones, I sell the last to upgrade to the newest. I've done it 4 years in a row).
3. Sit down and thing about whats important, buying to hoard things or having less that means more. I grew up with very limited funds, as an adult it's important to me I have a savings more than it is I have a bunch of crap I don't need.
This may help someone.
