The genius tip that will cure your jet lag – but you won’t enjoy the preparation

JET lag can ruin a holiday, as well as make you feel awful for days on end.

Many experts have their own ways of avoiding it, with one explaining it is all to do with drinking coffee at the right time.

Samantha Brown, who travels for a living as a TV host, said the key to avoiding jet lag starts days before travelling.

Sadly, caffeine addicts may not be pleased to hear it includes giving up coffee for a few days before heading off on holiday.

She told : "I try to limit caffeine a few days before I leave on a trip so it is totally out of my system when I land.

"I try to wait to have more caffeine until I'm about to collapse and that is when I allow myself to have a double espresso."

She continues: "The caffeine then hits my system so strongly because I am so depleted of it that I am able to go the rest of the day.

"I do that again when I return. It is like methodically taking caffeine so I get the strongest punch."

Limiting food and drink is way to avoid jet lag that is even used by government officials and the CIA.
