Paris on 5 euros per day?

I have decided to set myself the challenge of living in Paris on 5 euros per day for the entire month of April (and to anyone who has seen the prices here, I know you are laughing hysterically at the very idea, but it's not an April Fool's joke).  It's partly because I want to see if I can do it and partly because I am exceedingly poor this month (so I kinda have to do it), and this is why the tellers at my bank looked at me like I'm a crazy person (see yesterday's post) - because I asked them for a withdrawal from my account of 30 5€ notes.  I personally don't understand why that's such a peculiar request, but I promise you, it involved three tellers and another customer getting involved before they would believe what I wanted.  

Anyway, the rules of the challenge are as follows (and they're my rules because it's my challenge to myself, you can disagree with them all you want but I think they're fair):

1. The challenge doesn't cover my rent or phone bill for the month, which I have paid separately. The challenge is to cover transportation, food, entertainment and miscellaneous.

2. I can use up what I already have (ie - whatever food I have in the cupboard, fridge and freezer,  the money I had left in my wallet as of this morning, which was €16.20, and the five Metro tickets in there as well)

3. I can use any available freebies (ie - wine at gallery openings, food at parties, and the €17.36 per week I get in food vouchers as a benefit from my job, etc)

4. I have flexibility (ie - if I don't use one day's fiver, I can roll it over to the next day; and if I overspend one day, I can make up for it by not spending at all the next day.)

5. I have to lead a normal life; I can't hide at home to not spend money, I have to get out there and carry on, just in a verrrry frugal way.

So there it is - I will post normally every day but will also include a brief update on how the challenge is going.  Wish me luck!
