Before getting pregnant I used to drink at least one bottle of Diet Coke a day. Now that I am pregnant I have cut way back, usually to little or no caffeine each day. Recently I have been sleeping really bad and the lack of sleep is causing me to just drag at work and have headaches. The past three days I have had one bottle of pepsi each day. I worry because I don't want to get into the caffeine habit again and I know the caffeine isn't good for the baby. How much caffeine do you ladies drink each day? Do you think a bottle a day is too much?
