For lent I gave up coffee.  I actually felt drawn to do so even after lent started.  It was a random moment on my way to get coffee that I decided to give up my "life blood".  And let me tell you, it has been a looong couple of weeks.  I have really struggled with this fast...many times I wondered, "How on earth is this making me closer to God??"  But it recently hit me that if I thought about God as much as I think about coffee (now), then I would be thinking about Him A LOT.  So I've challenged myself that each time I think of coffee to say a prayer or just meditate on Him!
