Sleeping problems, jet lag and restlessness after a tiring flight are nothing new for the cabin crew community. To put all that behind you, put a little bit of lavender or eucalyptus oil on your pillow or use it when you take a bath. Lavender is well-known for its calming and sleep-inducing effects. 
Phatoil Lavender Oil is a pure plant extract and is available in 10ml bottles at the Cabin Crew Store.
