I am almost 2 weeks without caffiene.  I have a splash in my coffee in the morning, but everything else is out.  I quit smoking 6 years ago and  I swear Caffiene is harder than that.   My particular addiction has to do with Diet Mountain Dew, which I know is like drinking poison.  Unfortunately knowing its so bad has not stopped my drinking it.  Doesn't matter how many blogs, posts on facebook or news stories, I still look at a bottle of it longingly.  It's been almost 2 weeks, the headaches are over and yes I feel better, I don't eat as much and I don't crave sweets like I did, but today it's everywhere!  Every time I turn around there's a bottle or can of diet Mt. Dew sitting on a table or getting ready to be put in a machine...to be distributed Icy cold and refreshing
