Traveling first trimester and early 2nd

So I’m traveling for work right now and just looking for some advice! I am with students (I teach HS) for a week and am hoping for some motion sickness remedies? I am 8wks +1 and the flight was TERRIbLe! I puked by the time we landed...

Any tricks that have worked for you?

Then at 13 wks I’ll be leaving for Europe also with students. I have more chaperones with me this time so I think it’ll be okay in terms of my having support but I am so nervous about the long flight! 😱 any suggestions??
