Fatigue, mild nausea: Jet lag occurs when you travel east or westbound. Typically you feel fatigued, mild nausea, and have trouble with sleeping. It lasts a few days, often worse on the first day. Get out into sunlight and take melatonin if you are having trouble sleeping.

Jet Lag: Jet lag symptoms: Fatigue or sleepiness, decreased concentration, moodiness, GI changes (diarrhea, nausea or constipation), sense of not being well & sleep disturbance (insomnia or early morning waking).

Yes: There are many things that affect jet lag, two of the most important: flying west is harder on you than going east and consuming alcohol on the flight always makes it worse.

Sun & melatonin: Jet lag is the mismatch between your internal biologic clock and the external world.Your internal clock is set by sunlight, espeically morning and evening light as well as your body's natural sleep hormone-melatonin.Exposure to sunlight morning and evening and using melatoinin prior to sleep you can hasten your adaptaion.Jet lag causes decreased memory and analytic skills for the first few days.

Various factors: It depends on your direction of flight, and how many time zones you will cross. If only 1-2 time zones, you will probably be okay, but if 3 or more going east, you will need equilibration. You can help yourself by drinking water, moving around on the plane, staying away from alcohol & caffeine, and adapt to new time zone by being in sunshine. Can use melatonin .3 to 3 mg when you want to sleep.

Melatonin is a sleep trigger, if you don't take enough, it doesn't work at all while if you take too much it doesn't make you any sleepier. Most experience travelers find 6mg of Melatonin works best (may also be due to variablity of the various melatonin products on the market).
