Sleeping pills for long flights?

It depends on your doctor. Most sleeping pills are very strong medications and many doctors are reluctant to prescribe them to patients, some doctors will readily prescribe them. You might tell your doctor you have a extreme fear of flying, most anti-anxiety medications like Valium and Xanax also are prescribed for people with sleep disorders and will knock you out. Ambien and Stillnox are also prescribed for sleep with much less of a "hangover" effect the next day.
