How to experience poverty firsthand?

I want to do an experiment to see what it is like to live with a low-income or in poverty. The problem (well, a good thing actually) is that I am married, we both work, and have health insurance. I'm certainly not going to give up my job for an experiment so what can I do to do see what it's like to live with little money. I lived in South Chicago for a month in college but because I'm working I can't do that. I tried living on the amount food stamps pay each month but to be honest it wasn't that hard because I knew I could have my normal meals in a month. We volunteer at the local soup kitchen and do overnight watches at the homeless shelter, so I see poverty, but what can I do (keeping my job, etc) to experience poverty? Thanks
