Coffee and Caffeine FAQ

i have always drank coffee and never smoked, recently though, i have switched to all decaf coffee in order to prepare for pregnacy, (during which no caffeine is allowed) it took four days of excrutiating migrain to quit caffeine for me, despite the fact that i was only at one cup a day, but now that i am free i am quite happy, just wanted to see if decaf was safe for me. But because of the migrain, i must disagree with people who say that caffeine is not addictive, and that there is no withdrawl, maybe not for some people but most i know suffer a headache at least.
