Motion sickness

So I don't have my first doctors appointment till Thursday. I have been traveling, I have always taken motion sickness medicine such as Dramamine and it's worked great. On these recent trips I have no taken anything because I don't want to risk anything. These flights have been absolutely terrible because of it. I will be doing a lot of traveling for the next 2 months. I am dreading it because of how miserable I got. What medicines are safe to take!? Any help is much appreciated :)
