With my first baby, I didn't quit drinking coffee since I've never been one to drink more than 1 cup a day anyways.. although I did stop getting mochas at Starbucks and switched to Caramel Apple Spices because they just tasted better.
Now, my morning coffee is making me nauseous.
I'm going to try it tomorrow w/out coffee and see how I do.. hopefully I won't want to kill anyone at work.
