I haven't drank coffee in so long, I think I forgot the taste. Just kidding. The next time you're pregnant and you may be tempted to drink that cup of java, remember this study that was recently published by The American Journal of Obsetrics. The study shows that pregnant who drinks more than 200mg of caffeine (10 ounces of coffee or 25 ounces of tea) may double their chances of miscarriage. Do we need any more of a reason than that?
