I started taking Prozac about a month ago and I was super nauseous for the first week or so. All I ate was crackers, toast, peppermints, and Sprite. I found that I was less nauseous when I had food in my stomach. So even though I did NOT want to eat, I forced myself to eat just a few crackers and sip some Sprite and it made me feel a little better. I never threw up from it. It'll be okay.
