Walk to work if you can. Buy top ramen $5.00, drink water, and hold the last $20 until next payday. Stack at least $200 each check, put all of your change in a water jug, and spend out of envelopes. One for food, transit, drugs and alcohol, rent, utities, phone. Keep tabs of everything u spend. Get ur credit together so even if you get in a bind you have backup. I was in the same situation about 10 years ago.
