I might have one glass of tea every other day or so. Sometimes two a day, depending if we eat out.
With my second pregnancy, I was craving cokes and had at least two a day through most of it (and also had gestational diabetes with him - coincidence?). For some reason, it never occurred to me to buy caffeine free cokes (which is odd, since I grew up drinking only that kind), but there you have it. Maybe it was pregnancy brain at work :).
