My mantra is X A N A X...(seriously) I asked my doctor for it and they would give me enough to get through each take off. But you really should experiment with it first. Once when I took it, I was flying myself with my kids. I passed out across the three seats and my kids just sort of slid forward and made themselves comfortable all around me. I do remember vaguely the flight attendent asking my daughter if their mother was OK.

And I say that if the destination is worth it I'll fly there. I'm not missing out on an adventure because of fear! That's how I got to Europe twice. (Although I will admit that I did not go to the top of the Eiffel Tower, only the "second" floor, but hey I was there!) And Taxco is SOOOOOO lovely!!!!!!!!!! You will be fine!
