pjcarr, I was not cabin crew but flight deck prior to my retirement. I would not worry about your condition, nor would I volunteer it on a medical. Your sleep patterns will be totally disturbed anyhow on your overnights away from your base. Around about 0400 in Vacouver for instance, I would be wide awake and staring at the ceiling then fall asleep half an hour before call time at 0800 to get ready for the crew bus.
