Being a long haul commercial pilot for many years, I can recommend it. Many pilots I know use to crossing several time zones also use it. I use the sub-lingual 3mg variety about 30 minutes before going to bed. (1mg produces more than 100 times the amount of Melatonin produced by your pineal gland naturally). I fall asleep quickly (around 10 to 15 minutes) and there are no side affects the next morning. I refrain from extended use, but have used it 2 weeks in a row with no problems falling asleep when I quit using it after that period.
If you do use it, be sure to find a reliable, content controlled brand since many of them vary widely in the amount of Melatonin content...
Look,
