Nausea and Traveling

Keke • Mama of Daisy Evelyn, our beautiful Rainbow Baby 🌈 after Monochorionic Monoamniotic twin loss
I thought the nausea would be gone by now but it just seems to be getting worst. 13+1 with twins and my nausea in the AM and PM are terrible. I'm okay in the afternoon. I'm traveling from FL to CA (9 hours with one layover) and I'm so nervous because of the nausea. I'm on diclegis which tones it down, but I'm at a loss on what to do. What if I puke on the plane? What if I can't make it to the bathroom to spew? OMG, what if I puke on someone?! Uuuugh!!! 😩 Any suggests to help with airline travel?
