If you are concerned about running out, talk to your bank. There should be someone there who can advise you of ways to limit your access to funds. Since money was critical for me in college, I arranged to NOT have easy access to my savings (had to go in the bank and sign for everything, couldn't debit/atm it, or transfer on computer or phone), stocked money in short term CD's that came available when I was most likely to need them, and put a daily limit on what I could pull from the ATM. Banks can be really good sources of information in this regard. I had CD's, by my 2nd year, staggered to come available every month...so if I had a really bad shortfall I could go to the bank and sign it out, but if I didn't, I just rolled it over and knew it would be there next time I needed it. BTW- because that money wasn't easily accessible, I actually graduated having only accessed one CD....that money became the down payment on my first house. (That money was NOT loan money, though....it was earned income.) With loan money I might be tempted to pay back after developing an adequate buffer.
