1. Drink green tea
2. Avoid any unfamiliar foods, or places with bad food hygiene. I once walked into a salad bar, started to order, saw some flies, and immediately walked out. No excuses, no embarrassment. It’s simply not worth getting the shits for.
3. Take an effervescent vitamin in the 3 days leading up to your flight, during your flight, and in the 3 days after.
4. Make a habit of washing your hands before you eat.
5. Rest well. I keep a strong antihistamine on hand if I can tell that it’s really going to be an issue. Use with caution, it goes without saying.
6. Be prepared. I bring along OTC painkillers and lots of tea, just to be prepared.
7. Use anti-bacterial gel and wipes religiously.
8. Eat nutrient dense foods. Get those vitamins! Even if your options are limited, orange juice is better than nothing!
9. Get sunlight when you can. Vitamin D is good for mental health, but also seeing the sun will help adjust your circadian rhythm and stave off the jet lag.
10. Acknowledge when it’s all too much. In January, at the start of setting up the Mexico office, I developed cut, dry lips and painful blisters on the inside of my mouth, meaning I could barely eat. My doctor confirmed these were caused by acute stress. But even acknowledging that this was a problem helped monumentally, and gradually, those damned ulcers went away!
