I've read that people should get up and walk around every 15-20 mins in flight but I'm not so sure I can do that for an 11 hour flight. Then once I'm back in school to finish the year, I have 7 exams to take each ranging from 2-3 hours and of course I won't be able to bring a bbl pillow in the exam hall. I really want to get this bbl done soon but of course I want my results to be amazing, so I'm wondering if I would be better off waiting until after my exams to get this procedure done.
