Should repeat for longer time
First coffee in more than a week!
Not too bad, a few headaches and really wanted some by Thurs. But now I had it today and it doesn't taste as good. :(
On Day 4, missing my coffee!
25.07.2011: I am attempting this this week. Only water so far! (although i have only been awake for about 7 hours of the week so lots still to go!)
