This is an interesting experiment, but in my opinion it's unrealistic at this point to expect to be able to pay for everything you need (particularly local services) with Bitcoin, even in places where it's relatively popular.

Rather than trying to go a week with just Bitcoin expenditures, I would suggest targeting a certain percentage of your normal expenses to be in BTC--say 20% to start with--and repeating the experiment with higher targets as time progresses. In other words, if you normally spend $200 in a week, buy $40 worth of Bitcoins and limit USD expenditures to $160, and see what (if anything) you have to do without to meet your budget.
