nausea/vomiting
"I have generalized anxiety disorder and suffer from emetophobia. The anxiety causes stomach upset and the fear of throwing up increases the anxiety in a vicious cycle. My psychiatrist prescribed Zofran while I was trying out SSRI's to help me get through the first few weeks of side effects. I am now on Celexa with a lot less anxiety and only take Zofran as needed! It works great it just makes me feel sleepy. Haven't run into any constipation yet."
