The worst thing about being pregnant for me was that I totally lost my taste for coffee. It made me SICK. In all three pregnancies. I was so relieved after the babies were born to drink coffee again, and I’ve never tried nor wanted to give it up since. Coffee is one of life’s pleasures, it’s good for you, and it doesn’t lead to any detrimental or harmful behavior, except for needing to pee too much on a car trip if I’ve overindulged that morning.
