I once eliminated coffee (I do drink it again, but much less than I did before) and I am prone to migraines (at least at that time I was since I have been headache free for two years now, but that is another story). I knew there was a possibility of getting a big headache if I went cold turkey, so I weaned myself off over a two week period and experienced no adverse symptoms of withdrawal. I did this by reducing the amount I drank by 25% for a few days, then another 25% for a few days, etc. until I was down to about a third of a cup (a real cup, not a big ass mug) first thing in the morning. Then after a couple of days with that last bit, stopping altogether.
