Melatonin tablets: To overcome jet-lag, melatonin is best taken at approximately 10pm to 12pm of the time of the destination for a few days before your flight. For example if you are flying from New York to London (with a 5-hour time difference in advance), then whilst in New York you should take 3mg of melatonin between 5pm and 7pm local time for 2-3 days prior to your flight. This will be equivilant to 10pm and 12pm London time and when you arrive in London your body clock will be much better suited to London time. Thereafter take 3mg at bedtime thereafter. When you are ready to return the same can be done in reverse.
Cell Stat Plus capsules: Two capsules 1-hour before the flight, and 1 capsule each 3-4 hours of flight time. Cell Stat Plus contains resveratrol that will reduce blood-clotting risks and is more suitable than aspirin for (A) those who are sensitive to aspirin and (B) is not likely to induce any stomach bleeding as aspirin may.
Gamalate tablets: Two tablets 30-minutes before the flight and 2-tablets each 3-4 hours of flight time. Gamalate contains GABA, GABOB (and vitamin B6 and magnesium) these ingredients will help to mildly sedate and relax. Alternatively if you want to relax but be wide awake consider Picamilone two tablets 30-minutes before the flight and 1 tablet each 3-4 hours of flight time.
Silver Protein: Gargle with 1/8 ounce of oral silver 30-minutes before flight: Use the nasal spray and spray nostrils 30-minutes before flight and frequently (every 3-4 hours) during the flight: Upon arrival take oral silver 1/8 ounce 1 to 3 times daily for several days, (or continuously if the food and water supply is risky). The silver protein will destroy germs on contact and help prevent the possible infection from airplane "bad air syndrome." Meanwhile the silver cream may also be placed onto the hands to help prevent infection from contact with buttons, buckles and lavatory handles etc.
