I didn't have any my first trimester with my first pregnancy, and then after second tri went to having a cup of black tea in the morning, and sometimes a soda in the afternoon.

This time around (second pregnancy), I didn't cut my black tea in first trimester. I've had one tea so far, and am so sleepy and have such a long day/night still ahead of me, that I'm probably going to get a can of soda to get me through the rest of the work day. (Ugh, then I have an evening math class until 8pm. joy.)

How much did/do you have per day? I guess I'll just measure each instance in "units", so one unit can be your one caffeinated drink of choice.

Just for fun!
