Ok Monday through Friday I have one can of Coca Cola or Pepsi (I need caffeine to function at work) is that safe to drink it is only a 12 ounce can it sometimes it can take me up to 2 hours to drink it all. I do not like coffee or tea. I did not drink any caffeine on the weekends just during the week. Come December when I am stay at home mom I will most likely not drink it anymore. I will be 7 weeks tomorrow.
