Pregnancy and Emetophobia - vomiting during labor?

I’m 35 weeks and 4 days and have managed to make it this far without throwing up during my pregnancy. I came close a lot of times, but I think my fear of throwing up kept me from actually doing it. Now I’m getting really nervous about puking during labor.

I know it can happen from a lot of things, like Pitocin, the epidural, the pain itself, or meds if you end up getting a C-section. I just get so panicked if I feel like I’m going to throw up and I want to try to be as relaxed as possible during labor. The thought of vomiting scares me as much as the pain 😭 I’m planning to ask for Zofran right away so hopefully that helps. Any other advice or experiences anyone has had with nausea/vomiting??
