I cut out a lot of unnecessary stuff as well. I paid off my credit cards, got rid of my truck,. So no more insurance to pay, no more gas, nor more upkeep. Wow that thing was expensive:) Only thing I pay for is well except the rent, utilities, food, and such. My employer pays for my bus pass so I take the bus everywhere. To work, to the doctor, to the electrolysis, etcetera.
It really depends on what you want to sacrifice as in terms of money. What you can live without essentially.
