Cleanse?

I know I've said I don't believe in cleanses.  But for some mostly emotional reasons, I'm going to try one.
Week 1:  Ease into veganism.  I am making real cheesecake tonight and I will eat it.
Week 2:  Actual veganism.  Also cutting out alcohol, coffee, diet coke, etc.
Week 3:  Raw vegan.
Week 4:  All liquids.  If I successfully make it through the preceding three weeks and break a bad habit or two along the way, I'm treating myself to one of those juice cleanses where they deliver to your door.

If I make it through all four weeks, I am finally redecorating my bedroom.
