As I read this I was halfway expecting to hear you say you were moving back in with your parents.
If you didn't make draconian cuts in your budget you might be surprised how easy - and satisfying - the transition will be.
My parents wouldn't take me back. They always made it clear that they have a "no return" policy...
We had to make some cuts. Looking at our budget overall, we will have to spend about $2K less per year than what we spent on average over the past 6 years. It doesn't seem too bad except that I am also planning to pay a lot more for health care than we did over the past 6 years ($10K instead of $2K/year on average). So that's $8K/year that needs to be cut from other areas of our budget. Out of the past 6 years, our leanest year spending-wise was in 2008. Our retirement budget is set about $3,000 below that. Since I do not remember suffering from deprivation in 2008, I think it is possible (in 2008, our income increased dramatically and so, while we reined in our spending due to the state of the economy, we didn't really feel the need to be overly cautious about our spending).
