Daily budgeting absolutely does not work as a sole plan. You should look to cut/reduce all recurring expenses, invest whatever you have left over after loan disbursement into a place you won't "plunder" it, and make every penny count _without living miserly_.
What do I mean by this: Take the max possible in federal Stafford loans if you have unmet expenses or if liquidity is an issue. If you have plenty of cash, take the first 8500 and leave your already invested money alone. The interest rate on these loans right now is high relative to prime, but their fixed rate is guaranteed. Shop around for a loan provider. Most importantly, find someone willing to cut the 4 or 5% origination fee. If your school is a direct lender, you are screwed and have no way of getting out of it (to my knowledge?). Your school takes 5% extra for providing a worse service.
(Not a fidelity salesperson, just like their services and convenience. You may check the offerings at other institutions to see how they compare. They are cutting fees and improving all the time.)
If you've any money in a Fidelity account whatsoever, you'd do well to sign up for a mySmart Cash account. Ask your parents to spot you a minimum amount to buy into one of their better mutual funds (if you know what you're doing). Then with some paltry amount into a mutual, MySmart Cash becomes a free service (maybe it already is now? Have not checked). It provides free checking, a free debit card, and refunds your foreign debit charges. It advertises that it grows at 4x a traditional checking account, but it's still a measly 1.75% APY right now. I think Scottrade offers something similar. If you have $2000, it does better in a Fidelity account and makes you less likely to spend it. You can link this directly to your bank account to "refill" your daily purchases. The advantage is not that it's growing at 4x a normal checking, but that you are keeping it separate from your Starbucks, cafeteria food, etc.
Keep two debit cards (Bank and fidelity) and zero credit cards. Use the Fidelity card for unavoidables (rent, utilities, insurance). Use the bank's card for daily purchases (coffee, food, groceries, entertainment). Sign up for the online services for both of these things and track your spending without obsessing over it. You will be very, very surprised at how much you're spending on daily niceties. Some financial "gurus" have nicknamed this the "latte factor", and while I think most of their advice is comically simple, it is an appropriate term. Once you track these things and watch your spending, you will stop buying lattes.
Use cash on vending machines and places in which you feel unsafe using plastic. Check your debit card charges and holds frequently to make sure that no smaller businesses make a mistake or try to rip you off. When you quit using cash, you make yourself accountable for every purchase. Try it and see.
Or if any of your neighbors are ignorant enough not to secure their connection, just mooch off of it for free. That's what I did for six months at my old place. If they don't bother to secure their router (very easy, and it'll keep most people away), I'll just help myself.
Easy solution to cable internet: Meet your neighbors! Chip in 5$/month and promise not to do any uploading or illegal file sharing. Free internet.
Buy a SkypeIn number and a wireless handset. Let people call your PC if you *must* have a home phone. My parents recently moved to SE Asia and people can call them at a US based area code for free. The only cost to my parents being the 2c/min (or whatever) intra-US usage charge. It allows them to receive US based calls for nearly zilch. You can set this up to forward to your cell phone also. If it forwards to your cell, you are charged wireless minutes but not by Skype. Cheap home phone that only charges you when you use it.
Save more money:
Go renegotiate your car insurance. Stop insuring your audio equipment from theft. Get the following discounts if you qualify: good driver, good student, safety course, drive <10k mpy, and commute only a short distance. These can reduce your premiums by up to 20% or so.
