Has anyone else’s constant nausea gone away when you started treating your phobia?

What the title says. I’m about to start Prozac for the anxiety/ OCD piece, but I’m CONSTANTLY NAUSEOUS!! Like every day for a year it has been constant along with stomach pain and acid reflux. I have been to the doctor as well as a GI and all of my tests were normal. Just wanted to know if there is a way out of this anxiety-nausea cycle I’m in?
