Sipes it's ok...I threw up all over myself, my seat, the pillow I had, and the pillow of the person next to me at 3am on a red-eye (for me) from LAX to MEL a few weeks ago. And I was in a window seat. Everyone was sleeping and the cabin was dark. Dunno what it was, cause the food was great.
Haven't had any drink incidences YET...but I'd take any of the drink incidences over my issue! Thank goodness I had an extra set of clothes in my carry on.
