ok so i'm leaving from america to iran in a couple of weeks. I've done it before but it was pretty rough and i desperately needed a shower when i got to my final destination. I actually curled my hair before the trip so when i was done traveling it was all flat and greasy and unruly. I hated it. And how am i supposed to fall asleep sitting up? I just really want to avoid feeling like crap after all that traveling, can anybody help? How can i stay feeling fresh?
